Installation - (Power Cord, Thermostat)
The VTAC unit can be controlled by any remote elec-
tronic thermostat that can interface with RCBWYG
terminals. In terms of outputs, there are two types of
thermostats: mechanical and solid-state. Refer to the
manual provided with the thermostat for proper connec-
tions and settings.
A Remote Thermostat Terminal Block with remov-
able plug is located on the front of the chassis below the
touchpad Control Panel. It provides a connection for a
remote thermostat and energy management inputs
(any
type 24 Vac thermostat can be used)
.
NOTE: Ensure power to the unit is shut off prior to mak-
ing any electrical connections.
1. Remove the Remote Thermostat Terminal Block plug from
the terminal block receptacle and connect the thermostat
wires to the plug as indicated in Figure 17.
2. Re-insert plug into terminal block receptacle.
