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 setpoint for the additional stage is 29 °C and the hysteresis is 0.5 K
(one-sided), the additional stage switches on at 29 °C and off at 28.5 °C.
This parameter is only available if the "Cooling" 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 its force-position control, which is only deactivated when a new control value is received.
The cycle time for automatic sending of the control value is adjustable. Cyclic sending can also be disabled.
This parameter is only available if the "Cooling" 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 cooling stage setpoint. The setpoint refers to the cooling base
setpoint (comfort temperature for cooling) for the basic level.
Example: the cooling base setpoint is 26 °C. When the temperature exceeds 29 °C, additional cooling is activated
so that the room is cooled quickly again. In this case, set the "Level interval for basic level up to additional level"
parameter to 3°C. This parameter is only available if the "Cooling" or "Heat and cool"
control functions are used.
