“Draw an installation plan showing the placement of the mats, floor sensor, and lead wire(s) to the thermostat. The Warmup Foil heating system should be at least 6″” away from walls for laminate and 12″” away for carpet. ”
When you have multiple floor heating systems being powered that require more than 15amps, you can use an additional 3iE as a relay as opposed to purchasing a separate generic relay which Warmup can supply.
This Relay-25 fits in a standard single gang box. It is used in conjunction with the 4iE® Smart thermostat series as well as the Tempo thermostat, in order to expand the original 15 amp capacity. It is specifically designed for large applications beyond 800 sqft.
