Can I connect more than one Warmup heater to a thermostat?
Warmup floor heating thermostats allow multiple floor heating systems to connect to a single thermostat if necessary.
As long as all systems that connect to the thermostat do not exceed 15 amps, running multiple leads up the conduit to the thermostat location is completely acceptable. When layout out the mats, it is important to make sure that all the unheated leads reach the thermostat.
Note: More than two leads running to the thermostat require 3/4″ conduit. Installations exceeding 3 heaters may require a junction box to be installed.
Please refer to the installation manual for further details regarding your Warmup system.
