Fig. 9. Inserting wires in terminal block.

IMPORTANT

Use 18-gauge thermostat wire.

NOTES:

When used in a single-transformer system, leave

the metal jumper wires in place between R and Rc,

and Rc and Rh. If used on a two-transformer sys-

tem, remove metal jumper wire between Rc and Rh.

If thermostat is configured for a heat pump system

in the Installer Setup, configure changeover valve

for cool (O-factory setting) or heat (B).

For wiring to a W8835 Zone panel please refer to the product

data sheet included with the panel.

and cool system with single transformer

(1H/1C conventional).
