Assembly and installation instructions
Product features
The clock thermostat type 30155 permits the operation and temperature
control of 230 V electromechanical Katherm HK units.
Features:
- Operating mode switch OFF / MAN / Auto
- Fan speed selector switch 1 / 2 / 3
- Setpoint dial 5 - 30 °C
When the operating mode switch is n the OFF position, the room frost
protection function is activated. If the room temperature falls below
approx. 5 °C, the heating valve is opened and the fan is switched on
at fan stage 3. In MAN position, the fan speed can be specified at 3
parametrisable levels. In AUTO position, a fan speed is set automatically,
which is dependent on the difference between the target ad actual
temperature and the set proportional band. Fan switch-off delay is active
once the heating or cooling output has been switched off.
