Introduction

A room thermostat simply switches the heating system on and off as necessary. It works by sensing the air temperature, switching on the heating when the air temperature falls below the thermostat setting, and switching it off once this set temperature has been reached. Turning a room thermostat to a higher setting will not make the room heat up any faster. How quickly the room heats up depends on the design of the heating system, for example, the size of boiler and radiators. Neither does the setting affect how quickly the room cools down. Turning a room thermostat to a lower setting will result in the room being controlled at a lower temperature, and saves energy.

The heating system will not work if a time switch or programmer has switched it off. The way to set and use your room thermostat is to find the lowest temperature setting that you are comfortable with, and then leave it alone to do its job. The best way to do this is to set the room thermostat to a low temperature – say 18⁰C – and then turn it up by one degree each day until you are comfortable with the temperature. You won’t have to adjust the thermostat further. Any adjustment above this setting will waste energy and cost you more money. If your heating system is a boiler with radiators, there will usually be only one room thermostat to control the whole house. But you can have different temperatures in individual rooms by installing thermostatic radiator valves (TRVs) on individual radiators. If you don’t have TRVs, you should choose a temperature that is reasonable for the whole house. If you do have TRVs, you can choose a slightly higher setting to make sure that even the coldest room is comfortable, then prevent any overheating in other rooms by adjusting the TRVs. Room thermostats need a free flow of air to sense the temperature, so they must not be covered by curtains or blocked by furniture. Nearby electric fires, televisions, and wall or table lamps may prevent the thermostat from working properly.

Features

The RT310RF from SALUS Controls is a stylish and accurate digital thermostat with an easy-to-read Liquid Crystal Display (LCD). The Receiver is used for wiring connections and heat 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.

Installation

Note:  Please insert batteries into the RT310RF thermostat and it will power up..

DIP switch settings
The DIP switches are found on the rear of your thermostat and can be used to change the span (temperature accuracy) of your thermostat from the default +/-0.5°C to +/-0.25°C. This may cause your boiler to operate more frequently. The DIP switches are located on the back of the thermostat. ON +/-0.25°C, OFF +/-0.5°C. The span is the accuracy with which the thermostat operates when displaying your temperature. You can increase the accuracy by setting the span to +/-0.25°C, meaning that your thermostat will be sensitive to a quarter of a degree temperature change and will activate/deactivate the boiler.

Connecting the RXRT510 receiver
Unscrew the backplate of the RXRT510 receiver in order to do the wiring connections. After that please switch the receiver ON.

Button functions and keys
There are few user controls for the RT310RF, making this thermostat very easy to operate. These controls are shown below, along with a description of each of their functions. The temperature displayed on the LCD is the current room temperature. All teh LCD icons with a description are shown below.

Test Pairing Function
Make sure your devices are wired and the thermostat has batteries inserted. Switch receiver to ON. If you are using the RT310RF pack, the pairing between the thermostat and the receiver is already done. If you bought the RT310TX and RXRT510 separately then pair as follows. Please make sure that the Receiver is set on Auto.
Note:  Before beginning the process, switch the receiver On/Off and then On again to reset it (On/Off/On).

Testing the RF transmissions
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, but it is advisable to test the RF transmission from the intended thermostat location to the Receiver location before fixing the thermostat to the wall. To check the RF reception, follow the following steps:

1. Press the UP button on the thermostat until the set point temperature is higher than room temperature by a few degrees.
2. Wait for a few seconds. The Heat on (heat call) indicator should appear on the bottom left of the LCD on the thermostat.
3. Check the green LED on the receiver unit – it should be lit.
4. Press the DOWN button to adjust the set point temperature to be lower than room temperature.
5. Wait for a few seconds, and the Heat on (heat call) indicator should disappear and the green LED should switch off.
6. If at step 3 the green LED is not illuminated, press the TEST/PAIRING button on the thermostat and try to place the thermostat closer to the Receiver.
7. Repeat steps 1 to 5.

Installer Mode

Press and hold and  keys to enter the installation setting. The first setting is temperature display resolution selection – d01. Press  to enter the existing setting. The setting will start flashing. Press  or to change the temperature display resolution, wait for 10 seconds to confirm, then enter d02 (if you didn’t press to save your selection, the change will be confirmed after 10 seconds and the thermostat will return to normal mode). d02 is to set temperature offset,  press increase/decrease offset. To exit Installer Mode don’t press any key for 10 seconds, or press See the table below

Continue adjusting the d02 and d03 following the same steps as above. Once you have finished setting up all the parameters, press to exit to the home screen, or don’t press any button for 10 seconds and it will exit automatically. 

0.0°C
d03| Frost setpoint| 5.0°C-17.0°C| Set the Frost Point temperature| 5.0°C

Operations

Initial Power UP
After powering up, the thermostat is reset. During the system reset, all LCD icons are displayed for 2 seconds and the keys are locked. After that, all keys are unlocked and the thermostat is initialized. The software version is shown. The typical reset display is shown below.

The following table shows the settings of the RT310RF digital thermostat after Power on, or after the TEST/PAIRING button is pressed:

Reviewing Setpoint Temperature

When operating in Frost protection mode, the LCD will show a frost setpoint with the Frost Protection indicator displayed.

Press Backlight or wait 2 seconds without the key press to return to normal operation, room temperature will be displayed.

Adjusting setpoint
By changing the Setpoint temperature, you are permanently altering your temperature. You can change the set point temperature very easily while you are reviewing the set point temperature. Press the UP or DOWN keys repeatedly to change the temperature setting. The set point temperature will flash to indicate that it can be changed: the temperature will be changed in 0.5°C steps per key press. The RT310RF will return to Normal mode if no keys are pressed for more than 2 seconds. Once the new control has been implemented, the change is a permanent override until the new Setpoint is set again. The setpoint temperature cannot be changed if Frost Protection mode is enabled.

Frost Protection
Press the FROST  button to activate Frost Protection. The Setpoint temperature is automatically set to frost setpoint to prevent freezing. If the room temperature is lower than the frost setpoint, frost protection will be enabled. When Frost Protection is enabled, the user should not be able to press or adjust frost Setpoint temperature, this feature being accessible only in installation mode. Please refer to page 7 for more information on Installer Mode. Press the FROST  button again to deactivate Frost Protection.

Note:  The setpoint frost temperature can be reviewed by pressing the Up button once, but can only be changed in Installer Mode. For more information about entering installer mode, please refer to page 7.
