30 Flow sensor primary

■

Operation with temperature value of return tempera-
ture sensor in primary circuit, plus 3 K.

■

If the primary circuit flow and return temperature sen-
sors are both faulty at the same time, the message

"A9 Heat pump"

appears and the heat pump shuts

down.

Cause

Measure

Short circuit, flow temperature sensor, primary circuit
(heat pump brine inlet)

Check resistance value (Pt500A) at terminals X25.1/
X25.2: See "Controller and sensor PCB". Replace sen-
sor if required.

31 Return sensor primary

■

Operation with temperature value of flow tempera-
ture sensor in primary circuit, minus 2 K.

■

If the primary circuit flow and return temperature sen-
sors are both faulty at the same time, the message

appears and the heat pump shuts

down.

Cause

Measure

Short circuit, return temperature sensor, primary circuit
(heat pump brine outlet)

Check resistance value (Pt500A) at terminals X25.3/
X25.4: See "Controller and sensor PCB". Replace sen-
sor if required.

38 Flow sensor primary

■
