I have a kanmor controller installed in my home or building. How can I find the instruction manual?

Each kanmor product has a three-digit product number. Most controllers have the three-digit product number on the front; thermostats and room controllers will have the three-digit product number inside the wiring area. Once you find the product number you can locate the installation and operation manual or the user manual on the kanmor website. Every current product has a page in the products section with links to related brochures. Discontinued product brochures can be found on the product literature page in the kanmor library.

I have a kanmor thermostat or room controller that shows OPN or OPEN. What does this mean?

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. 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, find out the three digit type number of the thermostats (shown in wiring area), and then refer to the product Installation and Operation Manual that is available on our website. Once the issue has been corrected, it is recommended to change the thermostat to the User access level.

I have a kanmor controller installed and the building is too cool. How can I turn up the heat?

Boiler or mixing controllers have a ROOM setting that selects the approximate temperature in the building. The boiler controller 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.

On a three-button controller, 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.

On a four-button controller, 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.

I have a boiler controller and the building is too hot during mild outdoor weather (10 to 20°C). How can I turn down the heat?

During mild outdoor weather, the building can get too hot because the boiler must maintain a minimum temperature while operating to prevent damage. The controller 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.

On a three-button controller, 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.

On a four-button controller, 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.

In general, large apartment buildings can have the WWSD set to 12 to 18°C and residences can have the WWSD set from 18 to 20°C.
