HVAC Electronic Thermostat

Prepare and Connect the Thermostat

Installation

TURN OFF POWER TO THE SYSTEM AT THE MAIN POWER

PANEL TO AVOID ELECTRICAL SHOCK.

Installation should be carried out by an electrician or a qualified

technician.

1.1

Find a Location for the Thermostat

•

For a new installation, choose a location about 5 ft. (1.5 m) above

the floor and on an inside wall.

Loosen the captive screw

holding the base to the

module.

Gently lift the lower part of

the module to remove it

from the base.

Secure the base using the

wall anchors & screws.

Wire the thermostat.

•

Avoid locations where there are air drafts (top of staircase, air out-

let), dead air spots (behind a door), direct sunlight, concealed

chimneys or pipes, or air diffusers.

First Power On

To remotely activate the Unoccupied mode, the REM input allows

connection to an optional CT240/CT241 telephone controller, a

central timer or an alarm system.

When you power TH144 for the first time, it

runs a sequence of tests and resets itself,

which lasts approximately 10 seconds. The

default setpoint is 20°C (68°F).

A closed contact remotely activates the Unoccupied mode (see 4.1).

NOTE: The displayed ambient temperature

might be higher than the real ambient temper-

ature if you are holding the thermostat.

models

For the programmable models, open the thermostat’s door, and set

the time (Hour and Minute) and day (Day).

NOTE: Before you configure the TH144, make sure the thermostat

sits on the base for at least 5 minutes.

NOTE: To protect the compressor, TH144 has an On/Off delay of 2

or 4 minutes (default is 2 minutes) before starting or stopping the

system (see switch #4 in following section).

NOTE: Refer to the AC144-02 installation instructions for details on

how to connect the RTI to the thermostat.

NOTE: After first power-up, wait at least 5 minutes while the internal

battery is being charged before configuring TH144.

If you have modified your Heat and Cool setpoints, when you switch from

F to °C (or vice versa), the setpoints will revert to their default factory

values (see 2.2).

If your thermostat is a 3H2C model, switch # 3 can be used to configure

the thermostat as a 2H1C. However, if you have any other model, the

switch is used to lock the keypad.
