Multiple mats can be connected to
a single thermostat or relay. Refer
to Table 2 and Table 5 for details on
calculating the maximum number of
mats per control or relay.
The thermostat is not fully illustrated in these diagrams in order to simplify them. These
diagrams are given only as examples of how to properly connect multiple mats. Care must
be taken not to overfill a box. Be sure to use wire nuts that are the correct size for the
connections being made. Follow all codes for wiring.
All electrical work must be done by a qualified licensed electrician in accordance with local
building and electrical codes, and the National Electrical Code (NEC), especially Article 424
of the NEC, ANSI/NFPA70 and Section 62 of CEC Part 1.
