If your Weathermatic Controller has no display, it could be due to: * No power to the controller: Check the power wiring and breaker, and ensure the control panel is firmly closed. * No 24V power from the transformer: Replace the transformer, as the likely cause is power surge damage.
Why does my Weathermatic SmartLine® controller not turn on zone when expected?
Your Weathermatic SmartLine® controller might not be turning on a zone as expected for several reasons. The zone might be set to OFF; in this case, set the zone run time position. The dial might be set to SYSTEM OFF; turn the dial to RUN. It's possible that no zone run time or daily start time has been set, so program these settings. Omit times/days may be activated, so verify these settings. A rain or freeze sensor might have stopped watering, indicated by a red Sensor LED; if the sensor is faulty, replace it.
