We can only give you the full warranty if it is installed correctly in accordance with these instructions. The QH basic thermostat is a maintenance- free thermostat with a 2-year warranty on the electrical functioning of the elements.

THERMOSTAT CONNECTION

• The thermostat is an on/off thermostat and therefore cannot modulate. For the connections to your boiler, please consult your boiler manual.
• The two wires coming from your boiler must be connected to the COM (Red) and NO (Blue) terminals, see the diagram below.

SRVICE

Turning the thermostat on/off
Press the on/off button to switch the thermostat on or off.

Adjust hysteria

• The factory setting for the hysteresis is 1 C. For comfortable use in the
• Dutch climate we recommend a hysteresis of 0.5 C. See advanced settings item 2. See pages 3 and 4.

Temperature calibration
Check with an external thermometer whether the displayed temperature corresponds to the room temperature. If this is not the case, adjust the temperature displayed on the thermostat using the temperature calibration in the advanced settings item 1. See pages 3 and 4.

Set day and time

1. Turn on the thermostat.

2. Press the SET button for 5 seconds, the temperature display will disappear from the screen and the minute display will flash.

3. Set the minutes with the +/- buttons and press SET, the hours will flash.

4. Set the hours with the +/- keys and press SET, the day of the week will flash.
   Set the day of the week with the +/- buttons and press SET.

5. The day and time are now set.

Select mode
Press the PRG button to choose the desired mode, the thermostat has two modes:

1. Manual mode (MAN)
2. Programming mode (PRG)

Set program
The thermostat has a 5+1+1 programming function. This means that you must set the same program for Monday to Friday (period 1, days 1 to 5). You can set an individual program for Saturday (period 2, day 6) and Sunday (period 4, day 7). You can enter 4 switching points per period.

1. Turn on the thermostat.
2. Press the PRG button for a few seconds, the programming menu will appear on the display, days 1 to 5 will light up. This means that you are programming for these days. The current switching point is shown at the bottom right of the display. You can set 4 switching points per period.
3. Select the desired time of the switching point with the +/- buttons and press the PRG button.
4. Select the desired temperature and press the PRG button.
5. 2 appears at the bottom right, this means that you are now programming switching point 2.
6. Repeat steps 3 & 4 for all switching points from periods 1 to 3. So you set a total of 12 switching points.

Example of a program:

• Period 1
  • Monday to Friday (1 to 5)
  • Switch point 1234
  • Time 6:308:0018:0022:30
  • Temperature 21182116
• Period 2
  • Saturday (6)
  • Switch point 1234
  • Time 8:008:0018:0022:30
  • Temperature 21212116
• Period 3
  • Sunday (7)
  • Switch point 1234
  • Time 9:0012:0019:0022:00
  • Temperature 21212116

Advanced settings
Turn off the thermostat and press for 5 sec. Press SET to open the advanced settings. The screen will turn on and the menu below will open. Use the PRG button to scroll through the menu items.

Temperature calibration

1. If desired, you can correct the built-in sensor of the thermostat. This can be a solution, for example, if you want to equate the thermostat with another existing thermostat. The range you can correct the sensor is minus 8 degrees Celsius ~ 8 degrees Celsius.
2. Hysteresis Set the switch-on difference. The thermostat will switch on when the set temperature deviates from the measured room temperature by this value.
3. Temperature limit Set the desired maximum temperature that can be set. Adjustable between 25~60 °C. The factory setting is 35 °C. This is only for the type with external floor sensor on the receiver. Not applicable for central heating installations.
4. Program mode on the thermostat can be programmed for different days separately or the 5 working days and weekend days separately (5+1+1). 4 switching times can be set per day. See program setting instructions and preset program on page 2.
5. Frost protection The frost protection can be switched on or off. When frost protection is enabled, it can be set to a temperature between 3 ~ 10 °C. When frost protection is enabled, the heating will be switched on when the temperature drops below the set value. The heating switches off when the temperature is 2 °C higher than the set temperature.
6. Enable/disable open window detection When the thermostat detects a sudden drop in room temperature (factory setting 2 °C in 5 minutes) the heating will be switched off. The screen will show OP (OP mode enabled). The program will resume after 30 minutes (factory setting). The OP mode can be canceled by pressing any key. Turn this function ON (01) or OFF (00).
7. Open window detection: Time setting The open window detection switches on when a large temperature drop is detected within a short time, for example when a window is open. This time can be adjusted from 2-30 minutes. Factory setting: 5 minutes. The OP mode can be canceled by pressing any key.
8. Open window detection: Temperature drop The open window detection switches on when a large temperature drop is detected within a short time, for example when a window is open. The number of degrees by which the temperature must drop to enable the open window function can be adjusted from 2-4 °C. Factory setting: 2 °C The OP mode can be canceled by pressing any key.
9. Open window detection: Return to program The open window detection switches on when a large temperature drop is detected within a short time, for example when a window is open. After a few minutes the thermostat will return to the regular program. The number of minutes the thermostat waits to resume the program can be adjusted from 10-60 minutes. Factory setting: 30 minutes. The OP mode can be canceled by pressing any key
