Trouble-shooting guide
TROUBLE POSSIBLE FAILURE REMEDY
Thermostat inoperative Plug not connected Connect plug in socket
Water cools down during night -Selector switch not in AUTO
position
-One of retaining valves
of the system inoperative
(enables thermosiohon water
circulation)
-Set the switch to AUTO
position
-Check machine installation
We recommend installation of
motor actuated ball valve
When pump is active,
unplesant noise in installation
is heard
Retaining valve makes noise
(weak spring)
Replace nonreturn valve with
motor actuated ball valve
Irrespective of the
temperatures, pump is
inoperative
- Selector switch (2) in position
»OFF« - “T2max.”(1) set too
low(under 20°C)
- Set selector switch (2) to
AUTO position
- Increase T2max
Irrespective of the temp.,
pump is continuosly switched
on.
Selector switch (2) in “ON”
position
Set the switch to AUTO
position
When “T1” key(7) is pressed
Er1 appears
T1 sensor is interrupted Check T1 senzor
When “T1” (7)key is pressed
Er2 appears
T1 sensor is short circuited Check T1 senzor
Er1 is shown on display T2 sensor is interrupted Check T2 senzor
Er2 is shown on display T2 sensor is short circuited Check T2 senzor
Control light of the pump is on,
but the pump is inoperative
Pump bloked or cable of the
pump interrupted
Chek the pump and connection
to regulator
