Always ensure the AC mains power is switched off before installing or working on any

components (this includes replacing the batteries). Use only AA 1.5 V alkaline batteries in the

thermostat. Place the batteries into the battery slot located in the back of the thermostat. Do

not use rechargeable batteries.

Press MENU. Using UP or DOWN, adjust the

temperature and then

press SELECT.

OpenTherm Modulating Control is a method of control used by modern heating systems. Instead of

switching a boiler on and off at intervals, modulating control allows the amount of heat provided by the

boiler to be controlled to match the varying demand from the thermostat. This means the customer has

greater system efficiency, energy saving and room comfort from our heating controls.

I have the two page manual and cannot make head not tail of it. My heating is coming on unnecessarily when the temperature is 22 degrees outside and the radiators are scalding except for the hall radiator which is cold. I am so frustrated. Wish I had never had it installed!

I have changed the batteries and every icon on the display is lit up. I can't get beyond that. Pressing the buttons does nothing. I have tried the down button and boost for over 5 seconds for factory reset and that does nothing either.

Frequently Asked Questions about Salus RT 520 TX Thermostat

Our support team searches for useful product information and answers to frequently asked questions. If you find an inaccuracy in our frequently asked questions, please let us know by using our contact form.

What is the dead zone of a thermostat? Verified

Many modern thermostats have a dead zone. If the temperature deviates less than 4°C from the set temperature, the system will not heat or cool. This so called dead zone of the thermostat prevents the system from turning on and off too often, saving energy.

This was helpful (1588) Read more

What is the best place to mount a thermostat? Verified

The best place for a thermostat is approximately 1,5 meter above the ground. Never place the thermostat nead a radiator or other heat emitting equipment or in direct sunlight. Choose a room that is used often. In most cases this is the living room.
