Temperature constant (T-const)

Factory setting for domestic hot water circulator

The pump constantly adjusts to a set temperature T_setpoint.
Current temperature determination:

• Through an internal temperature sensor (not available with “-R7” version)
• Through an external temperature sensor which is connected to the pump

NOTICE

The control function T-const. can be used with an external sensor (e.g. PT1000) for “-R7” version. The external sensor is connected to the AI1 or AI2 analogue inputs.

The “internal sensor” as sensor source T1 or T2 is not available with the “-R7” version.
