3 Zone Panel Troubleshooting Steps |
| Step | Action | Check(s) |
| 1 | Turn off power to zone panel and remove cover. | |
| 2 | Verify E-Heat switch is in off position, and DIP switches are set properly.
The zone panel will not cool if E-Heat is switched on. | J |
| 3 | Ensure supply temp sensor is wired to terminals SA1 and SA2. Dampers will not
close and the zone panel will not stage if the SAS is missing or damaged | D |
| 4 | Ensure no zones are calling by turning all thermostats off. | |
| 5 | Apply 24 VAC Power to the 140303 3 Zone panel. | |
| 6 | Verify green power LED near 24 VAC Terminals is lit. | A |
| 7 | Verify green heartbeat LED in middle of panel is pulsing. | A-B-H-K |
| 8 | Verify all 3 zone LED's near damper terminals are green. | A-B-C |
| 9 | Verify Supply temp display shows current plenum temperature. | D |
| 10 | Switch zone 1 thermostat to heat mode, and call for heat in zone 1. | |
| 11 | Verify zone 1 damper LED stays green (open) and zone 2 and 3 damper
LEDs change to red (closed). | E-F |
| 12 | Verify heating system is operating, air is moving out zone 1 vents, and zone 2
and 3 vents have minimal airflow. | F-G |
| 13 | Verify supply temp display measures heat change in supply air. Switch zone 2
thermostat to heat mode, and call for heat in zone 2 by raising set
temperature above room temperature. | D |
| 14 | Verify zone 1 damper LED stays green (open) and zone 2 damper LED
changes to green (open). | E |
| 15 | Verify heating system is operating and air is moving out into zone 1 and zone 2. | E-F-G |
| 16 | If installed, switch zone 3 thermostat to heat mode, and call for heat in zone 3. | |
| 17 | Verify air is now flowing to zone 3. | E-F-G |
| 18 | Return zone 1 thermostat to the off position. Verify zone 1 damper LED turns
red and zone 2 and 3 damper LEDs stay green. | E-F-G |
| 19 | Verify heating system is operating, air is moving out zone 2 and 3 vents, and
zone 1 vents have minimal airflow. | E-F-G |
| 20 | Return zone 2 and 3 thermostats to the off position. Verify system fan shuts
off at the end of purge cycle. | H |
| 21 | Verify all zone LED's near damper terminals are green. | E-F-G-H |
| 22 | If the outside temperature is acceptable, repeat the above steps in cooling
mode. Cooling will not work if E-Heat is on. | |
| 23 | When checkout is finished, restore thermostats and retest entire system. | |
| 24 | If the above steps do not solve the problem, please contact Braeburn Technical
