Why does my Zonex Control Systems blower run continually?
- JJessica RuizAug 12, 2025
The controller might be in cool mode. To resolve this, initiate a thermostat call.
Why does my Zonex Control Systems blower run continually?
The controller might be in cool mode. To resolve this, initiate a thermostat call.
What to do if all Zonex Control Systems thermostats will not call?
A possible cause is a loss of 24V AC on R and C. You should repair the power source.
Why won't my Zonex DigiTract 4 initiate cooling cycle?
This issue may arise if the controller is in heat mode, in which case there will be a delay prior to changeover. Also, the controller may be in changeover from heat mode, and the 4-minute purge cycle must complete before cooling starts.
What to do if Zonex Control Systems zone dampers will not close?
The dampers might be incorrectly wired. To solve this, correct the damper wiring.
What to do if my Zonex Control Systems heating calls short cycle?
This can occur if the heating anticipator is incorrectly set; set the anticipator to the lowest setting. Also, the bypass damper might be opening prematurely; adjust the bypass damper closed with all zone dampers open.
What to do if Zonex DigiTract 4 cooling calls short cycle?
If the LAT is shorted (0V dc on + and – with LAT installed), replace the LAT. Alternatively, the LAT wiring might be shorted (0V dc on + and – with LAT installed); in this case, repair the LAT wiring.
What to do if my Zonex DigiTract 4 Control Systems zone damper remains closed?
The transformer VA may be too low. Replace it with a transformer that has the correct rating.
What to do if Zonex Control Systems triac shorted?
Replace the controller, and check 24 V AC.
