6. POSSIBLE ERRORS IN THE CONTROLLER OPERATION
6.1. A selected zone is not heating
–
closed valve or inactive pump
Check:
◼
Whether the heating season is switched on,
◼
Whether the correct date (day of the week) and time is set,
◼
Whether heating is active in the schedule for the current day of the week and time,
◼
In the system with a weather compensator
–
whether the outdoor temperature reading
is correct and whether the temperatures are set correctly,
◼
Whether DHW priority heating is switched off,
◼
In the system without room thermostat
–
whether it is switched off in the controller,
◼
In the system with a room thermostat
–
whether it is switched on and correctly
connected to the controller,
◼
Whether the mixer is not connected inversely and whether it is not jammed,
6.2. A selected zone is subject to overheating
Check:
◼
Whether the valve is not blocked,
◼
Whether the mixer actuator is operating,
◼
Whether the actuator cables are connected properly,
◼
The value of mixer dynamics.
