Installation

Thermostat Location
Install the thermostat approximately 5 feet (1.5m) above the floor in an area that has a good amount of air circulation and maintains an average room temperature. Avoid installation in locations where the thermostat can be affected by drafts, dead air spots, hot or cold air ducts, sunlight, appliances, concealed pipes, chimneys and outside walls

Install your new PROSTAT thermostat in 5 basic steps:

• Install the Sub-Base
• Provide Power
• Connect Your Wires
• Set Installer Switches
• Attach Thermostat to Sub-Base

Install the Sub-Base:

• Remove the sub-base from the body of the thermostat.
• Mount the sub-base as shown below:

Provide Power

• For 24 Volt AC power, you must connect the common side of the transformer to the C terminal on the thermostat sub-base.
• For primary or backup power, insert the 2 supplied “AA” type alkaline batteries into the battery compartment located in the rear housing of the thermostat. Make sure to position the Positive (+) and Negative (-) sides of the batteries correctly with the +/- symbols in the battery compartment.
