On a four-button control, press the menu button to enter the Adjust menu. The first setting is the ROOM setting. Press the up arrow button to increase the setting. Wait 20 seconds and the control will record the setting and go back to the View menu.

Pressure regulator valves come in two main styles: direct acting and pilot operated. The majority of residential water systems use direct-acting valves. These valves contain a heat-resistant diaphragm attached to a spring. When water pushes on the diaphragm with enough force, the pressure causes the valve to close more tightly.

When faced with insufficient pressure, don't immediately jump to the conclusion that your regulator valve has failed. You may simply need to have your valve adjusted. Virtually all pressure regulator valves have a pre-set pressure limit of 50 psi. Most homeowners consider this too little pressure.

The boiler control has an automatic warm weather shut down that turns off the boiler. Lowering the warm weather shut down setting will reduce or prevent over heating.

Both the boiler staging controls and the Mixing controls have a ‘Boiler Minimum’ setting to protect the boiler(s). The boiler and mixing controls are reading the boiler temperature at different locations, supply vs. return. Therefore, you must set the ‘Boiler Minimum’ setting on the mixing controls at least 20°F cooler than the ‘Boiler Minimum’ setting on the boiler staging control. Otherwise the mixing controls back off too soon while the boiler control thinks everything is okay.

In general, large apartment buildings can have the WWSD set to 55 to 65ºF (12 to 18ºC) and residences can have the WWSD set from 65 to 70ºF (18 to 20ºC).

Boiler controls have a ROOM setting that selects the approximate temperature in the building. The boiler control does not measure the actual room temperature so the ROOM setting is simply the approximate desired temperature in the building. To get more heat, increase the ROOM temperature setting in 2-degree increments until the building feels warm.

Theoretically, a plumber can dismantle a regulator valve and replace any defective components. Yet this strategy often ends up taking longer — and costing more — than simply replacing the valve entirely. Replacing your valve also ensures that problems stay at bay for as long as possible.

Mixing controls are designed to provide boiler return protection. On the control display, check the boiler temperature measurement in the View menu. Then enter the Adjust menu and check the BOILER MIN setting. If the measured boiler temperature is below the boiler minimum setting, the mixing control is designed to close the mixing valve or reduce the speed of the variable speed injection pump.

On a three-button control, press all three buttons together, then let go. You will enter the Adjust menu. The first setting is the ROOM setting. Press the up arrow button to increase the setting. Wait 20 seconds and the control will record the setting and go back to the View menu.

In most cases, a plumber can resolve this issue by disassembling and cleaning out your regulator valve. Soaking the valve in a calcium and lime remover loosens up and dissolves unwanted mineral deposits. After rinsing the components clean, the plumber reassembles the valve, which should now function without undue restrictions.

OPN or OPEN means that there is an open electrical circuit on an auxiliary temperature sensor input. In the wiring area, check to see if an auxiliary sensor has been connected to the thermostat. If there are no wires connected to the auxiliary sensor terminals, the SENSOR setting in the ADJUST MENU can be set to OFF to correct the problem.

At the top of a water regulator valve sits an exposed screw. This screw allows a plumber to alter the tension exerted on the spring inside of the valve body. Tightening the screw makes it more difficult for water pressure to move the diaphragm, thus raising the maximum pressure. Loosening the screw has the opposite effect.

In other words, the older a pressure regulator valve gets, the more prone it becomes to failure. Generally speaking, most regulator valves have a life span of between 7 and 12 years. If you have recently noticed any abrupt changes in the water pressure in your home, an internal component in your pressure regulator may have failed.

Alternately, low water pressure causes the diaphragm to remain relaxed, thus keeping the valve open more widely. Over time, the moving parts of this mechanism experience a significant amount of force. Eventually those components may succumb to degradation, making them less responsive than they should be.

On a three-button control, press all three buttons at the same time, then let go. The control is now in the adjust menu. Press and release the Item button until you find the WWSD (warm weather shut down setting). Then press the down arrow button to reduce the setting. Wait 20 seconds and the control will record the setting and go back to the View menu.

I have a boiler staging control and a couple of mixing controls (classic series). It doesn’t seem as if the mixing controls are providing enough heat and the building is under heating.

Why won’t my boiler(s) fire? I wired the control with power and connected my boiler to it but it is not turning on the boiler(s). The boiler does fire when I press the test button.

Each tekmar product has a three-digit product number. Most controls have the product number on the front; thermostats will have the three-digit product number inside the wiring area. If you are not sure, use this page to locate the product number of your control.

Fortunately, a professional plumber can measure your exact pressure setting and make adjustments to the regulator valve to optimize pressure. For more information about how to get the best results from your pressure regulator valve, please contact Seattle's plumbing pros at Aurora Plumbing.

Classic series tekmar controls require a call for heat, or demand, to be applied to the control. Check the display to see if a boiler demand is present, you may not have provided a demand to the control. Use the building thermostat, or end switches from zone valves or zone pump relays to apply either 24 V (ac) power to the demand terminals on the control.

Excessive water pressure — anything above 80 psi — can cause serious problems for a residential plumbing system. Ultimately, such pressure can damage water-using appliances and may even lead to leaks and the problem known as water hammer. Fortunately, you can keep your water pressure within a safe range by installing a pressure regulator valve on your main water line.

On the display the boiler control will show the outdoor temperature reading in the View menu. In some cases, the outdoor temperature is reading much warmer than the actual ambient outdoor air temperature. This results in the heating system using cooler water temperatures to heat the building.

Unfortunately, over time, a regulator valve may develop blockages that restrict flow beyond the intended amount. Such blockages often stem from high mineral content in your municipal water supply. These mineral deposits accumulate inside of the valve body, leading to lower-than-intended home water pressure.

A water pressure regulator valve works in much the same way as an outdoor hose faucet. A screw at the top allows you to increase or decrease the flow of water through the valve. Tightening the screw restricts water flow and hence places a tighter limit on the maximum water pressure.

On a four-button control, press the menu button to enter the Adjust menu. Press and release the Item button until you find the WWSD (warm weather shut down setting). Press the down arrow button to reduce the setting. Wait 20 seconds and the control will record the setting and go back to the View menu.

The location and installation of the outdoor air sensor on the outside of the building is very important. The outdoor sensor should be installed on a north-facing wall and away from any heat sources such as direct sunlight, vents, doors, and windows. Warm air from the building can travel from inside the building along the hole in the wall where the sensor wire is pulled. Ensure this hole is sealed using silicone or spray foam.

No, for classic series controls each control requires its own outdoor sensor. Example: Two 356 mixing controls, each require their own outdoor sensor 070.

Once you have your product number, enter it into the 'Search' box at the top of this website. The product page will contain everything you need to know about your product, including service bulletins, software updates and all associated user and installation manuals.

I have a mixing control and it shows a mixing demand but it will not open the mixing valve or the variable speed injection pump.

If there is a sensor connected, check the wiring for loose connections or broken wires. In some cases the auxiliary temperature sensor may have failed and requires replacement. For specific information, locate the three digit product number of the thermostat, and enter it below to view the product page. Refer to the product Installation and Operation Manual that is available on the Technical tab. Once the issue has been corrected, it is recommended to change the thermostat to the User access level.

However, professional and designer series communicating controls use a network to share information such as the outdoor temperature. Once a single outdoor sensor 070 is connected to a control or thermostat, the outdoor temperature is available on all products within the system.

As its name implies, a pressure regulator valve caps water pressure at a safe limit set by your plumber. While effective, this plumbing component may develop problems as time goes on. If your home contains a regulator valve, keep reading. This article takes a closer look at three common problems faced by water pressure regulator valves.
