Installing Thermotouch

Switch off mains power
You will be installing Thermotouch as part of a high-voltage mains electrical circuit. To ensure your safety and to protect the thermostat, switch off the main’s power before you start the installation.

Choose a location
At this stage, it is likely that an RCD-protected Electric Underfloor Heating system has been installed and an electrical plate is already in place. The Underfloor Heating cold tail should be pulled up through the electrical plate, and the sensor probe installed (in the conduit provided) within the wall cavity or pre-chased channel in a solid wall. The Thermostat can be mounted in a landscape or portrait position. Please note the default screen orientation is landscape so if mounting in portrait this will need to be changed in the settings once the unit has been powered up.

Maximum distances
Thermotouch can be installed up to 50m away from the Underfloor Heating system it is controlling, provided that the floor sensor is used to control the temperature. Underfloor Heating cold tails and floor sensor probes can be extended up to 50m.

Wiring diagram
Connect Thermotouch to the Underfloor Heating (UFH) cold tail, Heated Towel Rail (or another additional appliance), power supply, and floor temperature sensor. The floor temperature sensor is not polarity sensitive.

Fix to the wall
Insert a small flat screwdriver in the groove on the underside to leverage the face plate away from the back plate. Carefully disconnect the ribbon cable and align the Thermotouch with the mounting positions on the pre-installed electrical plate. Fix in place with the screws provided. Now connect the ribbon cable and clip the face plate back into position.

Heating modes

Thermotouch 4.3dC has several preset heating modes that can be adjusted in the settings menu.

Schedule
Thermotouch will adjust your Underfloor Heating according to your pre-set heating schedule. You can manually override the schedule using the up and down arrows to select a different temperature. Thermotouch will maintain the boost temperature until the next scheduled heating event.

Manual
You can manually select any temperature and must make all temperature changes yourself.

Holiday
Maintains a low frost protection temperature, usually between 5 – 10°C, while you are away. Your heating system is off but will switch on automatically if the temperature gets too cold. Please note this puts the entire controller into holiday mode which means that the towel rail will be off as well.

Eco
Maintains a low temperature, usually between 15-20°C, to save money on energy bills while keeping the chill off your floor.

Comfort
Maintains a higher temperature, usually between 20-28°C, which will keep you warm on a cold day! Both of these modes can be set to stay on forever until you change it, for a 1,2, or 4-hour boost, or until the next heating schedule event.

Set the time and date
When you first switch Thermotouch on, you will need to set the current time and date. You can do this by pressing Menu and then Date & Time. Use the arrows to select the right date and time and then press confirm to save.

Heating schedule
Setting up a schedule ensures energy efficiency and convenience by automatically changing the temperature of your Underfloor Heating system. There are 6 heating events every day. Most people treat them as 3 on/off cycles. All 7 days are programmed independently. If you don’t want to use all the heating events you can skip events by setting it to the same temperature as the previous event. Please note you will need to still ensure that all the times are consecutive and that the times do not run over midnight. Start setting up your underfloor heating schedule on page 18.

1. Press menu
2. Press schedule
3. Press UFH schedule
4. Press Monday
5. The first heating event for the day is already selected.
6. Set the time you want your heating to come on in the morning and the temperature you want your floor to heat up to, using the up and down arrows.
7. Use the arrows on the left-hand side of the screen (next to all the event times) to select the second heating event.
8. Now use the arrows to set your ‘OFF’ time and the Eco temperature. This is a low temperature that means your heating is effectively off. We recommend setting the eco temperature between 15-20°C.
9. Repeat steps 6 – 8 for heating events 3 & 4. If you don’t want your heating on in the middle of the day, set events 3 & 4 to the low Eco (or off) temperature.
10. Repeat steps 6 – 8 for heating events 5 & 6. If you don’t want your heating on in the evening set events 5 & 6 to the low Eco (or off) temperature. Please note however all times still need to be consecutive to ensure that the program runs correctly.
11. Press confirm to save your settings.
12. Now you need to set the heating schedule for the rest of the week. Press back and then select Tuesday.
13. Repeat steps 5 – 11 to set the on/off times and temperatures for Tuesday. Press confirm to save your settings.
14. Press back, select the next day, and repeat the steps to set a heating schedule for all days of the week.
15. Press confirm to save your settings and press back to go back to the menu and home screen.
16. 

The copy function is to copy the times from the Underfloor Heating schedule across to the Heated Towel Rail schedule. This does not copy from one day to the next. Each day does need to be programmed individually. When only using some of the on/off periods (i.e. only having the floor heating on once or twice a day) all the times need to be consecutive and the times cannot be over midnight.

Please note:
When the Thermostat is in portrait mode the heating times go down the two columns not from left to right.

Appliance controls
You can control another appliance, such as an electric Heated Towel Rail from the home screen.

On
The appliance will stay on until you turn it off again.

Schedule
The appliance will switch on and off according to the appliance heating schedule

Appliance boost
Switches the appliance on for 1 hour, 2 hours, or 4 hours and then reverts back to the appliance heating schedule.

Appliance schedule

The appliance relay is completely separate to the Underfloor Heating relay which allows you to have two completely separate schedules and allows one to be on without the other. However, if you want the towel rail on at the same time as your Underfloor Heating. You can copy your Underfloor Heating schedule, to the appliance (such as an electric Heated Towel Rail or mirror demister) that is connected to your Thermostat. When you have finished setting your Underfloor Heating schedule press Copy, press OK, and then press Confirm to save your settings . This will copy all of the on/off times from your UFH schedule to the appliance schedule. However, you will still need to set ‘ON’ or ‘OFF’ each time. Alternatively, to set up a separate schedule for the appliance relay follow the below steps:

1. Press the menu
2. Please schedule
3. Please HTR schedule
4. As per the UFH schedule, use the arrows to adjust the times of your schedule and select ‘ON’ and ‘OFF’ for each time selected. Please note all times need to be consecutive even if these periods are set to ‘OFF’.
5. Repeat for each day of the week
6. Press to save

Energy Saving Features

Adaptive Start
With the Adaptive Start feature enabled, Thermotouch will measure how long it takes for your individual floor to heat up and ensure the target temperature is achieved at the set time. So if you set your heating schedule to 24°C at 07:00, the floor will be at 24°C at 07:00. No need to set the heating to come on early! Thermotouch starts learning from the first time you enable the heating schedule. It turns on an hour early to start with and gradually optimizes the heat-up time over 7 days.

Open Window Detector
When the Open Window Detection feature is enabled, Thermotouch can detect sudden drops in temperature and will switch off your heating to eliminate wasted energy. Thermotouch will come back on after 30 minutes, provided the temperature has stabilized. You can activate and adjust these features in the advanced settings menu. See Page 24

Factory Reset

Factory Reset
To do a factory reset on the unit navigate to the menu screen and select the green advanced settings box. Use the arrows to move to page 3 of the settings. Use the smaller arrows next to Restore to change from ‘NO’ to ‘Yes’. Press the tick button in the bottom right-hand corner of the screen. The unit will take a couple of seconds to switch off and reset to factory settings. Do not touch the screen while it is performing the reset. This will totally erase the heating program and any adjusted settings. Please note that the current date and time that has been set will not be erased.

Locking Keypad
Locking The Entire Keypad
To lock the entire keypad navigate to the main home screen and press and hold the time in the top left-hand corner for approx. 4 seconds until a padlock symbol appears in the bottom right-hand corner next to the A/F. To unlock the keypad press and hold on the time again until the padlock symbol disappears.

Locking The Advanced Settings
Alternatively, you can lock just the advanced settings. This means that you can easily still change your program but ensures that none of the advanced settings are changed accidentally. To do this navigate to the menu screen and press and hold the green box for approx. 3 seconds until a padlock symbol appears in the top corner of the green box. This indicates that only the advanced settings are locked. To unlock the advanced settings you will need to be on the menu screen. Then press and hold the Thermotouch logo in the top right hand corner of the screen until the padlock on the green settings box disappears.
