Section 10. Wiring
Heaters can be controlled using several methods. Normally thermostats are used to control the heaters but they can also
be controlled by an Energy Management System. Figure 29 illustrates the connection for heaters controlled by a line
voltage thermostat NOTE: In order to use line voltage thermostats, the internal jumper connection located at the thermostat
connections inside of each burner must be connected to the blue and purple wires shown on Figure 33. Figures 30a & b
illustrate control schemes that incorporate a low voltage thermostat. For a single heater with a low voltage thermostat, use
Figure 30a. If it is desired to control multiple heaters on one low voltage thermostat, then use Figure 30b. To control
multiple heaters on one low voltage thermostat, the low voltage terminals on each heater must be connected to the internal
jumper connection as shown in detail. Heaters must be grounded in accordance with applicable codes: United States: refer
to National Electric Code ANSI/NFPA 70 - latest version Canada: refer to Canadian Electrical Code CSA C22.1 Part I -
latest revision.
