10.24.45 Alarm functions — Frost alarm temperature for HVAC and RHCC status (°C)
Options:
Setting option between 0 - 15
The RHCC status and HVAC objects have a frost alarm bit. It the input temperature of the
controller drops below the temperature set in this parameter, then the frost alarm bit is set in the
status objects. It is reset when the temperature is exceeded.
10.24.46 Alarm functions — Heat alarm temperature for RHCC status (°C)
Options:
Setting option between 25 - 70
The RHCC status object has a heat alarm bit. If the input temperature of the controller exceeds
the temperature set in this parameter, then the heat alarm bit is set in the status object. It is
reset when the temperature falls below the set temperature.
Note
The following parameters are available when the "Controller function" parameter
is set on "Heating with additional stage".
The same parameters are available which are also available when parameter
"Controller function" is set on "Heating" and parameter "Control value type" on
"2-point 1 bit, On/Off" or "2-point 1 byte, 0/100%".
Note
The additional parameter "Control value type" is available for the additional
stage.
10.24.47 Control of additional heating stage — Temperature difference to basic stage (x 0.1°C)
Options:
Setting option between 0 - 255
The setpoint temperature of the additional stage is defined as a function of the current setpoint
temperature of the base stage and is expressed as a difference. The value represents the
setpoint value starting at which the additional stage will operate.
