Hi All,
Last night i noticed that all radiators are cold, went to see valve an it was sitting on HW but didn't turn to HW&CH, when i manually turn the valve to HW&CH all radiators went hot and after reaching set temperature it come back to HW, when temperature went below set one and CH should turn on, it didn't turn.
so is not turning to HW&CH position but when i turn in manualy then it turn to only HW ????
Please Help,
Regards
