Hi,
I have recently replaced my old Sunvic SP 50 on a new Pro 2000. At the same time I have decided to replace a room termostat TLX 2259 on a new model TLX9201. Since then have noticed thermostat can't fire a boiler automatically. Temperature in the room is well below 20 when click on thermostat I can hear around 24 centigrades. To switch a boiler I have manually turn a knob above 24. Wiring for a new termostatis:
1 - Common (L)
2 - Satisfied
3 - empty
4 - Neutral.
What can be a reason? Thanks for your help!
