What does it mean if my thermostat reads “overload” on this display?


4iE Smart WiFi Thermostat

The overload message will occur if more than 15 AMPS has been connected to the thermostat. A second thermostat or a relay will be required to handle more than 15 AMPS. Please contact your local retailer or Warmup to coordinate ordering one of these products.
