5.0. CONTROLS

5.1 TPC multi-functional controller
Multi-functional controller with integrated zone valve, air vent, differential
pressure and PWH temperature controller.
PWH temperature control
direction the temperature is increased, by turning it in (-/MIN) direction
the temperature is decreased.
Setting range 40-60°C.
PWH temperature should be adjusted to 50 °C, as this provides optimal
utilization of DH water.
For systems with circulation, the hot water temperature must be 60 ° C and
the circulation return temperature must not fall below 55 ° C. (valid for DE).
Note: Systems with DHW circulation generate significantly higher heating
return temperatures in circulation mode than in full load mode
Differential pressure controller
The differential pressure controller equalizes the high fluctuations in pres-
sure arriving from the heat source, ensuring constant operating pressure
The following applies to all EvoFlat stations:
At the "HE" connection, the available differential pressure is - depending
on volume flow (40 - 645 l / h) - between 220 - 165 mbar.
Zone valve
The TPC multi-functional controller contains a zone valve.
The TWA-Q/NC actuator can be mounted on the zone valve.
The transport protection on the TWA-Z/NC actuator must be removed
before use.
5.2 Air vent
The station should be vented during start up.
