Demand offset
1x017
The desired flow temperature in heating circuit 1 can be influenced by the
demand for a desired flow temperature from another controller (slave) or
another circuit.
See Appendix “Parameter ID overview”
OFF:
The desired flow temperature in circuit 1 is not
influenced by the demand of any other controller (slave
or circuit 2).
Value:
The desired flow temperature is increased by the set
value in ‘Demand offset’, if the demand of the slave /
circuit 2 is higher.

The function of ‘Demand offset’ can compensate for heat losses
between master and slave controlled systems.

1x500
When the controller acts as a slave controller in a master / slave system,
information about the desired flow temperature can be sent to the master
controller via the ECL 485 bus.
Stand-alone controller:
Sub-circuits can send the desired flow temperature to the master circuit.
See Appendix “Parameter ID overview”
OFF:
Information about the desired flow temperature is not
sent to the master controller.
ON:
Information about the desired flow temperature is sent
to the master controller.
In the master controller, 'Demand offset' must be set to a value in order
to react on a desired flow temperature from a slave controller.
When the controller acts as a slave, its address must be 1, 2, 3 ... 9 in
order to send the desired temperature to the master (see the section
‘Miscellaneous’, ‘Several controllers in the same system’).

M exercise (valve exercise)
1x023
Exercises the valve to avoid blocking in periods without heat demand.
See Appendix “Parameter ID overview”
OFF:
The valve exercise is not active.
ON:
The valve opens for 7 minutes and closes for 7 minutes
every third day at noon (12:00 hours).
