The following table shows what each switch corresponds to depending on position.
Switch one should be set in the “OFF Servant” position unless you plan to broadcast
readings from remote temperature sensors to other thermostats in the system when
there is no control system in place.

Connecting the ViewStat to the HVAC System
Warning!
120 volts may cause serious injury from electrical shock. Disconnect electrical
power to the HVAC system before starting installation. This system is a
low-voltage system.
Improper installation may cause serious injury from electrical shock. This
system must be installed by a qualified contractor in accordance with NEC
Standards and applicable local and state codes.
