HWC pump GP11K4
Energy measurement kit (EMK 300)
The flow meter is installed on the supply line from
EB101 with the arrow in the direction of flow.
The temperature is measured using the installation's
existing sensor.

When heating is permitted, the shunt is controlled to
the calculated flow temperature and when cooling is
permitted the shunt is controlled to the minimum flow
temperature, in relation to supply temperature sensor
2/3/4.
The shunt valve controls the number of whole seconds
as the differential (calculated flow temperature 2/3/4
– supply temperature sensor 2/3/4) * shunt valve
amplification. The mixing valves open for even numbers
and close for odd numbers. The mixing valves are sta-
tionary during the waiting period 2/3/4.
