Battery Replacement

Battery Cover

Assembly

The UtilityPRO has a coin cell

battery that retains the time

and date during a power failure.

Under normal circumstances the

coin cell should last five years.

Should the time and date need

to be reset after a power failure,

this is an indication that the coin

cell needs to be replaced. You

should replace battery every five

years, or before leaving home for

an extended period.

Coin cell

battery tray

Insert the coin cell battery in the coin cell battery

tray and push it inside the battery cover assembly

The UtilityPRO is shipped from the factory with the coin cell installed. To keep the

battery from discharging during shipment and storage, the UtilityPRO is shipped

from the factory with a plastic tab inserted in the battery holder. This tab must be

removed before the thermostat is mounted on the wall. Simply pull the plastic tab

out of the thermostat. To replace the battery, remove the battery tray using a screw

driver. Place a new coin cell (type CR2032 or equivalent) observing the correct

polarity and push the battery tray into the battery cover assembly.

Demand Control

This is an energy saving device. At times, thermostat operation may be temporarily adjusted

by a small amount as outlined in your energy provider’s associated program literature. This is

normal operation and is part of the program for which you have enrolled.

Thank you for your participation.

Operating Manual

Utility PUr so a gF ee sa tures

Usage is a service provided by the utility provider. Depending on the various services

provided by the utility provider, Usage may contain vital information for your use. It

may display your electricity bill, water consumption bill, gas bill, and so on. Usage

also has a feature wherein you can compare your present consumption against

your last year’s consumption for the same time period. For example, it displays

your current electricity bill along with the previous year’s electricity bill for the same

month.

Usage also displays the rate of electricity at peak times and off peak times. Thus you

can adjust your electricity consumption accordingly.

Utility Messages

Messages are also a part of the services provided by the service utility provider.

Messages are sent by the service provider to assist you with additional information.

These messages may contain weather warnings, greetings, reminders, information

about discounts running at a shop, system maintenance messages, and so on.

Special Features

Auto Changeover: When set to Auto, the thermostat automatically selects heating or

cooling depending on the indoor temperature.

Adaptive Intelligent Recovery: This feature allows the thermostat to “learn” how

long the furnace and air conditioner take to reach programmed temperature settings,

so the temperature is reached at the time you set. For example: Set the Wake

time to 6 am, and the temperature to 70°. The heat comes on before 6 am, so the

temperature is 70° by the time you wake at 6. The message “Recovery” is displayed

when the system is activated before a scheduled time period.

Compressor Protection: This feature forces the compressor to wait a few minutes

before restarting, to prevent equipment damage. During the wait time, the message

“

Wait” is displayed on screen.
