Controlling Multiple Heaters with a Single Control Device
When multiple heaters are operated by the same control device (for example, common vented heaters), an
external relay kit (P/N: ERK) must be utilized (one per heater). This allows the heater's 24 V supply voltage to
be isolated from the external control voltage of the thermostats. The ERK is to be installed on or near the
heater. Follow the instructions that accompany the accessory for more information and wiring diagrams
