When the space heating/cooling control
is OFF by the user interface, the pump is
always OFF. When the space
heating/cooling control is On, you can
select the desired pump operation mode
(only applicable during space
heating/cooling)
Pump operation mode:
Q
0 (Continuous): Continuous pump
operation, regardless of thermo ON
or OFF condition. Remark:
continuous pump operation requires
more energy than sample or request
pump operation.
Q
1 (Sample)(default): The pump is
ON. When there is heating or
cooling demand as the the leaving
temperature has not reached the
desired temperature yet. When
thermo OFF condition occurs, the
pump runs every 5 minutes to check
the water temperature and demand
heating or cooling if necessary.
Remark: Sample is NOT available in
extended room thermostat control or
room thermostat control.
Q
2 (Request): Pump operation based
on request. Example: Using a room
thermostat creates thermo ON/OFF
condition. When there is no such
demand, the pump is OFF. Remark:
Request is NOT available in leaving
water temperature control.
