position
-One of retaining valves
of the system inoperative
(enables thermosiohon water
circulation)

(weak spring)
- Selector switch (2) in position
»OFF« - "T2max."(1) set too
low(under 20°C)
Selector switch (2) in "ON"
position

REMEDY
Connect plug in socket
-Set the switch to AUTO
position
-Check machine installation
We recommend installation of
motor actuated ball valve
Replace nonreturn valve with
motor actuated ball valve
- Set selector switch (2) to
AUTO position
- Increase T2max
Set the switch to AUTO
position
Check T1 senzor
Check T1 senzor
Check T2 senzor
Check T2 senzor
Chek the pump and connection
to regulator
