CRTP2 Room Thermostat
17. Installer menu
To access the installer menu, you must hold OK and
When in the installer menu, press
Normal Mode (Nor)
When the thermostat is in Normal mode, the thermostat will try to reach the
target temperature after the program changes.
Example: Program 1 on the thermostat is 21°C for 06:30am and the room
temperature is 18°C. The thermostat will start the heating at 06:30am and the
room temperature will start to increase then.
To return to main menu, press OK to select Nor
Optimum Start Mode (OS)
When the thermostat is in Optimum Start mode, the thermostat will try to
reach the target temperature by the start time of the next switching time.
This is done by setting the Ti (time interval) on the thermostat in this menu
to 10, 15 or 20. This will allow the thermostat 10 mins, 15 mins or 20 mins to
increase the room temperature by 1°C.
Ti can be set when OS is selected in the installer menu.
To return to main menu, press OK to select required Ti
To achieve the target temperature when the program starts, the thermostat
will read:
1. The Room Temperature (RT)
2. The Setpoint Temperature (ST)
3. The Target Temperature Di erence (TTD) is the di erence between
the setpoint temperature and the room temperature .
The time (in minutes) that it will take to overcome (TTD) is called Optimum
Start Time (OST) and its maximum value is 3 hours = 180 mins. This is
subtracted from the start time.
As the temperature increases the thermostat will recalculate the OST if the
temperature is increasing too quickly.

Program 1 on the thermostat is 21°C for
06:30am and the room temperature is 18°C.
The thermostat will start the heating at
05:30am to reach 21°C for 06:30am @ Ti=20.
