7.5.6. Modbus slave address
When integrating the SchwankControl heating control into an existing building management system [BMS],
each connected control unit requires a unique Modbus address.
The control unit address corresponds to the address set on the address selector switch of
the HeatControl: Address 1...8.
The control unit address can be set manually.
Address 0 = auto... 254
7.5.7. Temperature time program OFF
This setting applies to all zones of the control unit. The selected setpoint temperature of the corresponding
zone is always active in automatic mode if all of the assigned time programs are in the OFF state.
7.5.8. Temperature time program ON
This setting applies to all zones of the control unit. The selected setpoint temperature of the corresponding
zone is always active in automatic mode if at least one of the assigned time programs is in the ON state.
7.5.9. Water meter
When operating a hybrid system, the value of a water meter pulse is specified here.
The parameter unit is litre/pulse [l/pulse]
7.5.10. Hybrid switch-off
When operating a hybrid system, the maximum permissible flow temperature is specified here. If this
temperature is exceeded, the circulation pump is switched off, the bypass is opened, and an error is displayed
by the control unit.
The parameter unit is degrees Celsius [°C]
7.5.11. Fan error display.
If a digital input is used for fan monitoring, the maximum time permitted to elapse between the switching on of
the fan and the acknowledgement of the enable can be set here. If this time is exceeded, the control unit
indicates an error.
The parameter unit is seconds [s]
7.5.12. Control unit - factory settings
