Thermostat 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. Using UP or DOWN, navigate to Hot Water submenu and press SELECT.

If you want to make a change, press UP or DOWN on the relevant screen. Using UP or DOWN, set the minutes and then press SELECT. When lines appear, press SELECT to confirm the removal of that specific interval TPI (Time Proportional & Integral) is a self-learning, time- proportional algorithm. TPI type of regulation ensures economical system operation through more accurate temperature maintenance during controlling process and limits overload conditions. In addition to the exact and stable room temperature, the advantage of this system is the minimization of energy consumption and significant savings. RT520 offers 3 types of TPI control: 1. for radiator (6CPH); 2. for underfloor heating (3CPH); 3. for electric heating (9CPH). Optimum Stop calculates how long the house will take to cool down, then turns off the boiler at the earliest possible moment, this means the system is not running when it’s not actually necessary. If there is a sudden heat loss during this period, then Optimum Stop will be overridden to regain comfort conditions. Landlord settings is a pin code protected feature that allows the landlord to set a service reminder on the thermostat that will warn the tenant when the boiler is due its annual service. Span is the difference between the measured temperature and the set temperature. The schedule has 6 time intervals for which different temperatures can be adjusted. You can set 2, 3 or up to 6 temperatures per day. You must define all time periods. Here is an example of setting a certain time with a certain temperature. If you do not want to use the 6 temperature intervals / day (ex: 1 eco, 2 comfort), please see below how to delete one or more intervals. If you are using the RT520RF pack, the pairing between the thermostat and the receiver is already done. During the pairing process, please make sure the thermostat and the receiver are at least 1 meter from each other. If you bought the RT520TX and RXRT520 separately or if you want to re-pair thermostat with the receiver, make sure that the device is disconnected from the power supply and the switches on the receiver have been set to AUTO and ON. Then connect the receiver to the power supply and wait for the red LED to light steadily. Then switch to the OFF position and again to ON position quickly. The red flashing LED will confirm entering the pairing mode. Once devices are successfully paired, LED on the receiver will go solid red. After all, thermostat will go back to the main screen. The device will be reset and will start up automatically. To reset the thermostat, press MENU, DOWN and BOOST simultaneously for 5 seconds. Repeat the process for all time periods. Once service mode has become active, the device will lock the set point temperature as set by the installer/landlord. To unlock this device, the landlord needs to be contacted and the boiler serviced. Landlord settings will not be reset.
