The parameters "Gap of additional stage" and "Hysteresis (one-sided)" enable you to specify when the additional
stage switches on and off. For example, if the additional stage setpoint is 18 °C and the Hysteresis (one-sided) is
0.5 K, the additional stage will activate at 18 °C and will deactivate at 18.5 °C.
This parameter is only available if the "Heating" or "Heat and cool" control functions are used.
Cycle time heating control value sending 0...60 minuti (0 – inactive)
Options:
- 0 / 1 / 2 / ... / 60
The room thermostat can send a control value, even if the value remains unchanged. This is often required since
the connected actuator may assume that the room thermostat is no longer available. This enables the actuator to
activate position check.
Cycle time for the automatic sending can be set. Cyclic sending can also be disabled.
This parameter is only available if the "Heating" or "Heat and cool" control functions are used.
Additional control value interval (0...127)x0.1°C
Options:
- 0
- .........
- 30
- .........
- 127
Temperature range 0..127 corresponds to 0C..12.7C
The parameter allows you to specify the additional heating stage setpoint. The setpoint refers to the heating base
setpoint (comfort temperature for heating) for the basic stage.
Example: the heating base setpoint is 21 °C. When the temperature drops below 18°C, an additional heating should be
activated so that the room is heated quickly again. In this case, set the "Level interval for basic level up to additional
level" parameter to 3 C. This can be necessary after an automatic night setback, if the user wishes to use
the room immediately (e.g. the bathroom early in the morning).
This parameter is only available if the "Heating" or "Heat and cool" control functions are used.
