What if my heating load exceeds the 16 amps that one stat can handle?

The Warmup Thermostats have a resistive load of 16 amps and may be used with any of the Warmup® systems.

If you want to control more than 16 amps worth of heating via a single thermostat, you will need to use Warmup® master thermostat & relay configuration.

The relays require their own separate electrical feed, and up to 10 relays can be daisy-chained to a single master unit via low voltage cabling.
