INSTALLATION

Recommended locations for your thermostat.
To ensure that your thermostat provides accurate readings and controls effectively, it must be installed approximately 1.5 m above floor level on an inside wall, away from direct sunshine and any other sources of heat or cold such as radiators, cold draughts, etc.
Important: The thermostat measures the temperature of the place where it is installed. It does not take into account the temperature differences  that may exist between different locations in the house if the temperature is not uniform.

For best performance, do not mount the thermostat on metal wall boxes and leave at least 30 cm distance from any metal objects including wall boxes and boiler housing.

MOUNTING OF WALL MOUTING PLATE

The digital room thermostat is fixed on the wall with the standard wall plate which is supplied with the product.

  1. Unscrew the 2 screws under the thermostat.

  2. Remove the wall plate from the thermostat.

  3. Secure the wall plate with the two screws provided using the horizontal and vertical holes.

  4. In case of surface mounting, a knock out area is provided on the wall plate and on the corresponding area of the thermostat.

WIRING

All electrical installation work should be carried out by a suitably qualified Electrician or other competent person. If you are not sure how to install this thermostat consult either with a qualified electrician or heating Engineer. Do not remove or refit the thermostat onto the backplate without the  mains supply to the system being isolated.

OPTIMISATION EXPLAINED
WHAT IS OPTIMISATION — OPTIMUM START?

Historically, most UK heating systems waste vast amounts of energy by firing unnecessarily early for most of the year. Homeowners tend to set their boiler on times based on when they wake up by guessing what time they feel that their boiler should fire in order to reach the requested target  temperature; for example turning the boiler on at 6am in order to have a warm room/ home by their wake up time at 7am.

Dual function  optimisation, priority to comfort or energy savings, the choice is yours: Depending on various parameters: room inertia, ambient  temperature, desired temperature, the thermostat calculates and optimises the programming for each heating period whether set to Comfort or  Savings (Eco):

In OPTI COMFORT mode, priority to comfort
In OPTI COMFORT mode, the thermostat’s inbuilt algorithm optimises in order to guarantee maximum comfort during the COMFORT programme.

The processor within the thermostat starts the boiler operation at the optimum time to achieve the setpoint temperature at the start of the occupancy period.
In this mode, the priority is given to anticipating and maintaining the comfort temperature during periods of occupancy.

In OPTI ECO mode, priority to energy savings
In OPTI ECO mode, the thermostat’s inbuilt algorithm optimises in order to guarantee maximum energy savings throughout the ECO programme.

In this mode, a slight drop in the temperature level at the beginning and end of the comfort period is allowed to maximise energy savings.

PLEASE READ BEFORE PROGRAMMING THE THERMOSTAT
Instead of using a fixed start time, Optimum Start calculates how long the house will take to warm up depending on the temperature of the home,  then fires the boiler automatically at the most efficient moment in order to reach your target temperature by your programmed time.

HOW DOES OPTIMUM START WORK?
Optimum Start works on a daily basis. You set the time that you want to be warm and Optimum Start will do the rest; for example – if you wake up  at 7:30AM, then set your thermostat’s start time for 7:30AM. Optimum Start ensures that you are warm when you want to be (and not before),  reducing wasted energy and saving money (up to 10% of energy costs).
To change the optimisation type, refer to the installation instructions/ advanced installer settings.

Note: To restore factory settings, press and hold down this part for more than 3 seconds using the tip of a pen.

All LCD display will be turned ON for 2 seconds and the factory settings will be restored.

TROUBLESHOOTING

The boiler is not heating:

  • Check that the Thermostat is calling for heat if yes then the thermostat would appear to be working check that the boiler has not switched itself off.
    If no increase set temperature.

  • In the event of a power failure or the thermostat being disconnected, the thermostat will maintain it’s programmed settings for up to 10 Hours.

The room temperature is not high enough, the boiler is not providing enough heat:

  • Check the active operating mode (see page 3) – the room thermostat may be in an Eco, Standby or Auto Mode entailing a temperature drop.
  • Check the active desired temperature and increase it if needed (see page 3).

The temperature in the room is lower than the setpoint temperature:

  • Check the programming. The thermostat could be in a scheduled Eco period.
  • Ensure that the time displayed is the same as the current time.

You made a mistake while setting:

  • You just need to restore factory settings, as explained in the “Factory settings” section (see page 4). This will reverse any changes you might  have made.

The system is not heating but is on:

  • If **** and indicator light is on but the system remains cold, then you should contact your installer.

The thermostat is programmed and you observe a delay between the active mode Comfort or Eco and your requirement:

  • The optimisation function can generate slight offsets to guarantee the level of comfort at the right time or to save energy by slightly anticipating an Eco passage.

Heating comes on before programmed start time and comes off after programmed end time:

  • Thermostat maybe set to OPTI Comfort mode. The thermostat will start the boiler at the optimum time to achieve the set point temperature  at the start of the occupancy period. (On cold days your heating may come on earlier than expected in order for the programmed occupied  temperature to be achieved).
  • To change the optimisation type, refer to the installation instructions.

Heating does not come on at programmed start time and comes off  before programmed end time:

  • Thermostat maybe set to OPT] ECO mode. The thermostat will stop the boiler at the optimum time to slightly reduce the set point temperature before the end of the occupancy period. (This helps you to save money on your heating bills).
  • To change the optimisation type, refer to the installation instructions.
    If the problem persists, then contact your installer.
    If either Service due soon or Service due appear in the display then contact your installer or land lord.

TECHNICAL SPECIFICATIONS

In the event of a power failure or the thermostat being disconnected, the thermostat will maintain it’s programmed settings for up to 10 Hours.

NOTE

In some instances the unit may have been set with the service interval function enabled. By Law in rented accommodation, your gas boiler should  be inspected/serviced annually to ensure it is working correctly.
This option is designed to remind the end user to contact the relevant person to have the annual service carried out on the boiler.
This function will be enabled and programmed by your Installer, maintenance Engineer, or Landlord.
If it has been set to do so, the unit will display a message on the screen to remind you that a boiler service is due.
The Service Due Soon countdown will be indicated up to 50 days before the Service is due to allow time to arrange for an engineer to attend,  normal functions will continue during this stage.
At the end of this service due soon period, the unit will go to Service Due OFF at which point only the 1hour boost will operate on the thermostat, it will operate at 20°C during this hour.

WHAT IS AROOM THERMOSTAT

…an explanation for householders 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 18°C — 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, wall or table lamps may prevent the thermostat from working properly.
