Sunvic 12570 Programmable room thermostat

What is a programmable room thermostat?
A programmable room thermostat is both a programmer and a room thermostat. A programmer allows you to set ‘On’ and ‘Off’ time periods to suit your own lifestyle. A room thermostat 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. So, a programmable room thermostat lets you choose what times you want the heating to be on, and what temperature it should reach while it is on. It will allow you to select different temperatures in your home at different times of the day (and days of the week) to meet your particular needs.

Turning a programmable 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 the boiler and radiators. Neither does the setting affect how quickly the room cools down. Turning a programmable room thermostat to a lower setting will result in the room being controlled at a lower temperature, and saves energy.

The way to set and use your programmable room thermostat is to find the lowest temperature settings that you are comfortable with at the different times you have chosen, and then leave it alone to do its job. The best way to do this is to set low temperatures first, say 18°C, and then turn them up by one degree each day until you are comfortable with the temperatures. You won’t have to adjust the thermostat further. Any adjustments above these settings will waste energy and cost you more money.

If your heating system is a boiler with radiators, there will usually be only one programmable 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. The time on the programmer must be correct. Some types have to be adjusted in spring and autumn to the changes between Greenwich Mean Time and British Summer Time. You may be able to temporarily adjust the heating program, for example, ‘Override’, ‘Advance’ or ‘Boost’. These are explained in the manufacturer’s instructions. Programmable 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.

INTRODUCTION

The SunStat is a wired programmable room thermostat. A SunStatRF should be purchased if a wireless (RF) version of the same unit is required.

Thermostat position
The thermostat should be placed at a height of 1.5m from the floor. Do not position on an outside wall, above a radiator, next to a door, or in direct sunlight.

For fixed wiring only
Disconnect the mains supply before attempting to wire the unit, or removing the unit from the back plate. A switch having a contact separation of at least 3mm in all poles must be incorporated in the fixed wiring as a means of fully disconnecting the main supply. An appropriate fuse should also be fitted to the circuit.

WARNINGS
All installations should be carried out by a competent person and in line with current wiring regulations. The covers must not be removed from any part of the units before the electrical supply has been isolated. Interference with sealed parts will render the guarantee void.

3. Press or to set the correct hour.
4. Press the to set the minute.
5. Press or to set the correct minute.
6. Follow the same procedure as above to set the “year” and then “month” and “day” respectively.
7. Press again if further changes to the clock are required.
8. When satisfied that the clock has been set correctly press to confirm & save the changes.
9. Any delay of longer than 15 seconds when setting the clock, will result in the unit returning to normal operation without saving the changes

Set / Adjust Clock
It is possible to set 4 different programs for each day of the week. Each program comprises 1 temperature and time set point. 4 symbols are used to differentiate the programs.

The thermostat will hold the room temperature at the required set point within each programmed time zone. At the next programmed time zone, the temperature can be changed, if required, to different temperature settings. The program resolution is in 10 minutes intervals. The first interval of the day starts at 00.00 is the last interval of the day starts at 23.50. The programming is designed to allow users to “overlap” time zones if required. If an “overlap” is selected the number of programs will reduce the number of “overlaps” For example if the start-up time of P3 is the same as the start-up time of P4, then the P3 operation will become an invalid command.

Program default settings

Program No	On Time	Temperature
P1	06.00	21.0°C
P2	08.00	18.0°C
P3	16.00	21.0°C
P4	23.00	17.0°C
