Questions and answers
why wont my boiler start and go off via the time clock it is set to auto
Your Danfoss 102E5 boiler may not be starting and stopping according to the timer set to auto due to several possible reasons:
1. Incorrect Programming – Verify that the programmed ON and OFF times are correctly set.
2. Manual Overrides Active – Check if the +1HOUR or ADVANCE override buttons are activated, as they can temporarily alter the schedule.
3. Unit Set to OFF – The ADVANCE function does not work if the unit is set to OFF, so ensure it is in AUTO mode.
4. Power Supply Issues – Confirm that the unit is receiving power (230V supply).
5. Wiring Issues – Ensure all wiring connections, including zone valves and thermostats, are properly connected.
6. Battery Backup Failure – If there is a battery backup issue, the unit may lose programmed settings and not function as expected.
7. Faulty Unit – If the above checks do not resolve the issue, the unit itself may be faulty and require inspection or replacement.
Check these factors to diagnose the issue and restore proper operation.
