ErP RATING
This product has been rated as Class 1, Efficiency 1%
The ERT20RF from SALUS Controls is a stylish and accurate dial thermostat. This thermostat has been specifically designed to be used for both Volt Free and AC heating applications that can replace most common residential thermostats and is designed to be used with electric, gas, or oil heating control systems. Unlike ordinary single-unit design thermostats, this is a new type of thermostat separating the operational functions into two units. The receiver is used for wiring connections and on/off control. The thermostat provides the user interface and temperature sensing/control. The two units are linked together by a Radio Frequency (RF) signal.
General Features
Please read the important safety information at the start of this manual before you begin to install the device.
Thermostat
The ERT20RF Thermostat is easily installed using the back plate supplied with the unit – this is used purely for mounting purposes, as no wiring is needed for the thermostat. The back plate can be mounted directly to the wall surface. The ideal position to locate the ERT20RF Thermostat is about 1.5m above floor level. It should be mounted in a location where the thermostat is accessible, reasonably lit, and free from extremes of temperature and draughts. Do not mount the thermostat on an outside wall, above a radiator, or in a location where it may be subjected to direct sunlight. To ensure a trouble-free operation of the Radio Frequency (RF) signal, always ensure that the thermostat is mounted away from any possible sources of interference (such as radios, TV sets, computers, etc.), and is not mounted on or in close proximity to large metal objects. Installing the ERT20RF in enclosed areas such as cellars and basements is not recommended
For replacing the batteries reverse the process in step 3. When the batteries need to be replaced the LED below the dial will flash
NOTE: All electrical installation work should be carried out by a suitably qualified Electrician or another competent person. If you are not sure how to install this digital thermostat consult either with a qualified electrician, heating engineer, or your boiler/heating system supplier for advice on how to continue. The ERT20RF Receiver should be mounted in a suitable location that is both accessible for the connection of mains and control wiring and allows good reception of the RF signal. The Receiver needs a 230V AC mains supply to operate, and this should be fused appropriately (13A max.). The Receiver should be mounted in a location where it will not come into contact with water, moisture, or condensation. The Receiver ON/OFF switch is accessible from the front face of the receiver, as shown in this picture:
On the front cover of the receiver, you will see that there is an ON/OFF switch and two LEDs. The bottom LED (RED) will illuminate when the switch is in the ‘ON’ position and the unit is receiving power. The top LED (GREEN) illuminates when the receiver unit is receiving a heat call transmission from the thermostat. The wiring terminals are located on the rear of the receiver, as shown in this picture:
RECEIVER WIRING TERMINALS
| 1 | NO | Normally Open [N/O] |
| 2 | COM | Linked Live feed (230V AC heating applications only) |
| 3 | L | Live feed (230V AC) |
| 4 | N | Neutral |

PLEASE DO NOT SWITCH THE RECEIVER ON UNTIL YOU ARE READY TO PAIR IT WITH THE THERMOSTAT
RF PAIRING
Switch on the receiver and the RED LED should start flashing. If the receiver was already switched on, switch\ OFF then back ON again the RED LED should start flashing. Now press and hold the SYNC button on the rear of the thermostat for 3 seconds. The LED below the dial will start flashing. Now check the LED on the receiver, once RF pairing is successful the LED on the receiver will stop flashing Now press and hold the SYNC button on the thermostat for 3 seconds. The thermostat should now be paired with the receiver.
It is important to site both the receiver and thermostat in locations where the RF signal cannot be interrupted. The receiving range between the thermostat and receiver is approximately 30 meters indoors, however, many factors can affect the RF transmission and shorten the operating distance, e.g. shielding by thick walls, foil back plasterboard, metal objects such as filing cabinets, general RF interference, and so on. The range is generally large enough for most household applications, to check the RF reception, follow the following steps:
If you are unable to get a stable RF connection between the receiver and thermostat, check that the receiver is both switched on and has a mains supply (red LED illuminated). If this isn’t a problem then try pairing the thermostat to the receiver again. See page 8.
CONFIGURATION
Your ERT20 thermostat is configured for HEATING control and simple ON/OFF switching, however, it can be configured for COOLING. This is easily done by changing the “jumper” setting. The “JUMPER” peg is located on the rear of the ERT20TX.
SETTING ROOM TEMPERATURE
The temperature can be changed by rotating the dial. The position of the dial allows the user a clear indication of the required room temperature and the status of the heating system.
When the ERT20RF is demanding heat. The red led below the dial will glow. When the correct temperature has been reached then the LED will go out.
Temp set for 15ºC
If the LED is flashing continuously in normal operation then the batteries need replacing.
FROST PROTECTION
Set the dial to 5ºC this will provide protection from freezing temperature
The ERT20RF electronic thermostat requires no special maintenance. Periodically, the outer casing can be wiped clean using a dry cloth (please DO NOT use solvents, polishes, detergents, or abrasive cleaners, as these can damage the thermostat). There are no user-serviceable parts within the unit. Should the ERT20RF electronic thermostat fail to function correctly, check:
