OPERATION

With Intellicomfort CH141A is possible to extract a programmable thermostat’s body from the frame after mounting and connections, this for doing more easily the adjusting or programming with the device in hand. With Intellicomfort CH143A isn’t possible to extract the programmable thermostat’s body.

The programmable thermostat has:
6 front keys to access directly the operating modes that can be changed by pressing the corresponding key.

VISUALIZATION

•  Ambient temperature
•  Current time
•  Temperature profile is shown by means of histogram
•  6 icons for programming

OPERATION MODES

MAN
The programmable thermostat regulates the room temperature using the set temperature within 24 hours.

AUTO

• The programmable thermostat regulates the prescribed temperatures according to the schedules on weekly profile.
• It has 1 winter program and 1 summer program (prescribed).
• In automatic mode can be set three temperature levels T1-T2-T3:
  • T1 can be set from 2 to 40 °C.
  • T2 can be set from 2 to 40 °C.
  • T3 can be set from 2 to 40 °C.
• Antifreeze temperature -Ta it is set from 0 to 7 °C.

Note: T3 cannot be less than T2 and T2 cannot be less than T1.

HOLIDAY

• The programmable thermostat follows time and temperature settings of the day “H”.
• This mode stops when it is selected another operating mode. The programmable thermostat has a predefined mode – Holiday, equal to Saturday and Sunday.
• In Holiday mode can be set three temperature levels T1-T2-T3.

JOLLY

• The programmable thermostat controls the installation using a set temperature over a period of time ranging from 1 hour to 240 hours.
• At the end of the set time, the programmable thermostat returns to the previously used operation mode.
• This function can be excluded at any time by setting a different operation mode.
• Example: Automatic Mode – Jolly for 1 week – the programmable thermostat completes the period of Jolly and resumes the automatic mode.
• T1: The temperature set manually from 2 to 40°C.

OFF (turned OFF)
This mode is used to manage system operation for maintaining the antifreeze temperature, set from 0 to 7°C.
Complete turn-OFF of the system T1=OFF.
