System Overview

To achieve the best control from the unit and thermostat, we recommend they are used with the SALUS system receiver configured to RX1. The system receiver will turn the boiler on or off when requested by the thermostat. See your boiler receiver manual for more information about the RX1 configuration.

The unit is modulating, which means it opens or closes partially or 100% depending on the relationship between the actual room temperature and the required room temperature measured by the VS10/20RF.

Up to 6 units can be connected to a VS10RF/VS20RF

Checking the compatibility of your heating system

If you can not see any thread on the valve and it looks like this picture, you may be able to use the RA adapter supplied. TRV10 fits 30x1,5 mm thread.

Our RA adapter also fits this valve.
Once fitted the RA adapter should look like this.

Preparing to Pair the Unit

1. Press and hold the button on the Universal Gateway for five seconds. This puts the Universal Gateway in pairing mode. See your Universal Gateway manual for more information.
   
2. Ensure the wireless thermostat is powered up and ready for pairing. See your thermostat manual for more information.
3. If you are using the optional RX10RF wireless boiler receiver configured for remote boiler switching, ensure this has been powered up and the red LED has gone from flashing to steady. See your boiler receiver manual for more information.

Pairing the Unit

Press and hold the pairing button for 10 seconds. You can pair up to 6 units with one thermostat. Pair the units room by room.

You have paired the unit to the thermostat when the unit LED goes off. Once paired, the unit operates in automatic mode and receives room temperatures from the thermostat.

INTRODUCTION

The TRV10RFM is a battery-powered, mini-size thermostatic radiator valve (TRV) controller using ZigBee wireless communication. Simply replace the existing, passive head on the standard radiator valve with the TRV10RFM (referred to from now on as the unit). Use the unit with the VS10RF or VS20RF series of wireless thermostats and a Universal Gateway.

Using the Unit

Auto Lock Function
Auto lock function is disabled until you have gone through the pairing process. After pairing, the TRV will auto lock after 5 minute if no buttons have been pressed.

Unlocking the Buttons
To unlock the buttons, press the pairing and close buttons together for 3 seconds.

Opening the Valve Manually
Press the open button for 3 seconds. The LED flashes green once and the valve opens.

Closing the Valve Manually
Press the close button for 3 seconds. The LED flashes red once and the valve closes.

Entering Fail Safe Mode
In fail safe mode, the unit opens the valve 25% for water flow to maintain room temperature.

To enter fail safe mode, press and hold the open and close buttons together for 3 seconds.

• Pairing button to put the unit in automatic mode
• Open button for 3 seconds to open the valve
• Close button for 3 seconds to close the valve

Restoring Factory Default Settings
Press the pairing, open, and close buttons together for 10 seconds.

Protecting against Frost
When you have manually closed the valve, the unit automatically enables frost protection. Frost protection starts only when the temperature in the room drops below the frost temperature setpoint. The unit does all this automatically when connected to a thermostat and you don't have to do anything.

Detecting Open Windows
The unit checks the rate of temperature drop in the room in which it is located. If the drop is rapid, it assumes a window in the room has been opened. This only works if the unit is paired to the thermostat and is in automatic mode and the battery in the unit is not low. The unit does all this automatically when connected to a thermostat and you don't have to do anything. It works between 0 and 40⁰C.

Protecting against Lime Scale
Do not leave a valve open for a long time because this could cause a build up of lime scale. The unit has a lime-scale protection feature to prevent against this. The valve motor automatically starts once a week if no valve movement has been detected within a 14day period. Lime-scale protection will continue to operate in automatic, manual open, and manual close modes and you don't have to do anything.

Auto Adaptation
Once the batteries are inserted into the unit, the red light will appear. If no keys are pressed it will auto adapt to the valve.
