Read This First Before Installing Thermostat

19

IMPORTANT

1

Read the entire installation section of this Installation

Manual thoroughly before you begin to install or operate

your thermostat.
• Remove the mylar label from the display window.

INSTALLATION

2

All installation is normally performed at the thermostat.

OPERATION

3

This Hunter Thermostat is designed to operate with

most single and multistage heat pumps having 24V

controls. The system will control two stages of compressor
and two stages of auxiliary heat. The relay current is limited
to 1.0 amps for each stage.

COMPRESSOR PROTECTION

4

The thermostat provides a 4-minute delay after shutting

off the compressor before it can be restarted. This fea-

ture will prevent damage to the air conditioner compressor
caused by rapid cycling. It does not provide a delay when
there are power outages.

TEMPERATURE RANGE

5

This thermostat can be programmed between 40°F and

90°F. However, it will display room temperatures from

32°F to 99°F.

POWER FAILURE

6

The thermostat is fully battery operated and does not

require power from the control circuit. Whenever the

main power is interrupted or fails, the battery power retains
the programs and current time.

BATTERY WARNING

7

When the batteries are low, “LOW BATT” indicator on

the display will flash. When this happens, install new

batteries (do not use old batteries) as soon as possible. The
batteries should last one year.

CAUTION: The batteries are the only source of power used to operate the system. If the batteries are not replaced,
the display will dim and the heating and cooling system will stop operation.
