SPECTRA COMMERCIAL AND RESIDENTIAL INSTALLATION GUIDE
Installation
Position the thermostat backplate against the wall so that it is level and the thermostat
wires protrude through the middle of the backplate. Mark the position of the backplate
mounting holes and drill holes with a 3/16" bit. Install supplied anchors and
secure plate to the wall. Thermostat wire must be 18 AWG wire. Shielded wire is recom-
mended when running parallel to line voltage wires or conduit for more than 1 foot. Strip the
wires back 1/4" (longer strip lengths may cause shorts) and insert the thermostat wires into
the connectors as shown in Figure 13. Tighten the screws to insure tight connections. The
thermostat has the same type connectors, requiring the same wiring. See instructions
enclosed in the thermostat for detailed installation and operation information.
