Instructions for installation and use

10.0 Commissioning and start-up, VX Solo HWS

10.1 Programmable room thermostat / DHW time controller TP9000

TP9000 (not part of delivery)
A programmable room thermostat / DHW time controller TP9000,
which allows heating and DHW operation according to demand,
must be placed in a reference room.
The integrated room thermostat will open/close a zone valve for
heating operation, and the DHW sensor in the cylinder or the DHW
timer will open/close the zone valve for DHW operation.
When there is no demand for heating or DHW all zone valves primary
and secondary are closed. And pump P1 is not running.
When the room thermostat calls for heating the primary zone valve M1
and the secondary zone valve M3 will open. Pump P1 will be switched
on. Zone valve M2 for DHW will remain closed.
When there is no heat demand all zone valves will close. And pump
P1 is not running.
When the sensor in the DHW cylinder calls for demand or the DHW
timer calls for demand the primary zone valve M1 will open, and sec-
ondary zone valve M2 will open and secondary zone valve M3 will close.
Pump P1 will then be switched on.

Danfoss Heating
Zone valves / thermal actuators TWA-A
Heating and DHW operation is activated by the programmable room
thermostat / DHW time controller TP9000 in connection with a zone
valve /thermal actuator TWA-A.
The thermal actuators of the zone valves are switched on by an ex-
ternal contact from the room thermostat, and start to open or close
the valves. The actuating movement is achieved by means of an
electrically heated expansion element. When the heating current is
switched off, the actuators shut or open the valves.
The actuators are equipped with a visual position indicator to show
the open or closed position of the valves.
