Warning!
The device may only be opened and installed according to the circuit diagram on the device or these instructions by a qualified electrician. The existing safety regulations must be observed. Appropriate installation measures must be taken to achieve the requirements of protection class II.
This independently mountable electronic device is designed for controlling the temperature in dry and enclosed rooms only under normal conditions. The device confirms EN 60730, it works according to operating principle 1C.
The easy 3p electronic clock thermostat is designed for room temperature control in conjunction with:
The clock thermostat is designed to control the room temperature. In the automatic mode, a changeover is effected between comfort and setback mode by the built-in timer. In setback mode, the green indicator lamp lights up. If the room temperature drops below the set value, heating will start, the red indicator lamp will light up.
Indicator lamps
Red indicates when the controller demands heat, Green indicates when setback mode is activated. Red flashing for failure.
The operating voltage is to be switched OFF and ON again.
Temperature setback of other temperature controllers
Temperature setback inputs of other temperature controllers can be connected to time switch output (terminal 28).
They are then controlled by the time switch.
The position of the mode selector switch (see 6.6) influences this output accordingly.
Controller heat demand at PWM
If the room temperature drops below the set value, the heating mode will start. The controller output is in the form of pulses of varying length (PWM). The length of the pulses depends on the difference between set and the actual room temperature.
The sum of pulse and pause times can be selected with J4 (between 10 or 25 min.).
If there are large temperature differences, the controller will switch ON or OFF permanently, e.g. when changing over to temperature setback mode. Use PWM only at current ≤10 A.
For inert applications (e.g. burners) we recommend a long cycle time.
For quick applications (e.g. electric direct heaters) we recommend a short cycle time.
For inert applications (e.g. burners) we recommend a long cycle time.

Plug-in jumper J4 (right side of board) | Time |
Double-pole jumper connection | 25 min (as-delivered condition) |
Single-pole jumper connection | 10 min |
Heat demand of the controller at ON/OFF regulation
When the room temperature drops below set temperature the output will be switched on, whereas it will be switched off, when set value is exceeded.
Plug-in jumper J3 (right side of board) | Regulation |
Double-pole jumper connection | ON/OFF |
Single-pole jumper connection | PWM (as delivered condition) |
The controller should be arranged in a place within the room which:
