The RTH110B non-programmable thermostat can be used to con-

trol:

• a gas, fuel oil or electric furnace - 2 or 3 wires

• a central air conditioner - 2 or 3 wires

• a hot water system with or without pump - 2 wires

• a millivolt system - 2 wires

• a central heating and cooling system - 4 or 5 wires

Note: This thermostat is not compatible with heat pumps or multi-

stage systems.

Features

• System operating mode selection: heat, cool or off

• Fan operating mode selection: automatic or on (continuous)

• Programmable heating and cooling cycle lengths: 10, 12, 15, 20

or 30 minutes

• Temperature display in °F or °C

• Backlit display

• Battery replacement indicator

• Interchangeable faceplates (titanium, charcoal & taupe)

2.1 Removing the Old Thermostat

IN ORDER TO AVOID ANY RISK OF ELECTRIC SHOCK, CUT

POWER TO THE HEATING SYSTEM.

nRemove the old thermostat to access the wires.

Attention: If the old thermostat was mounted onto an electrical box,

it was probably powered by 120/240 volts. In this case, this thermo-

stat cannot be used.

oIdentify and label each wire (with the corresponding letter on

the wire terminal) and remove them from the terminals.

pIf necessary, strip the end of each wire (maximum of 1/4 inch).

qWrap the wires around a pencil to prevent

them from falling into the wall.

rIf the hole in the wall is too big, insulate it

using a non-flammable material in order

to avoid air draughts behind the thermo-

stat.

2.2 Installing the New Baseplate

For a new installation, choose a location approximately 5 feet

(1.5 m) above the floor and on an inside wall. Avoid draughty

areas (top of staircase, air outlet, etc.), dead air spots (behind

doors), direct sunlight or areas near concealed pipes or chim-

neys.

nRemove the thermostat faceplate.

oLoosen the locking screw to separate the thermostat from its

baseplate (the screw cannot be completely removed).

pTilt the thermostat upwards.

qMark and bore the appropriate mounting holes (using a 3/16”

drill bit) or use the existing holes. Insert the plastic anchors.

rPass the wires through the opening of the baseplate and fix the

baseplate to the wall using the screws provided.

2.3 Connecting the Thermostat

Refer to the following table for matching the wire labels with the

thermostat terminals.

Note: Do not connect wires identified as C, X or B. Wrap the bare

end of these wires with electrical tape.

Important: The red jumper wire between Rh and Rc terminals must

be removed in a 5-wire installation.

2.3.5 4-wire Heating and Cooling

2.3.6 5-wire Heating and Cooling

Note: Remove the red jumper wire between terminals Rc and Rh.

2.4 Setting J2 Jumper

The jumper specifies how the fan will operate

when it is placed in automatic mode (see sec-

tion 3.2).

2.5 Installing the Batteries

nPull out the battery cover.

oInstall the batteries as shown. Observe the polarity.

pReinstall the battery cover. You will hear a clicking sound.

After the batteries are installed, the thermostat performs a series of

tests for approximately 5 seconds.

Afterwards, the screen displays the actual tempera-

ture. It is normal that the displayed temperature will

be higher than the ambient temperature if you hold

the thermostat in your hands. It will display the

ambient temperature after the thermostat is

installed on the wall. By default, the setpoint is 70°F (21°C).

2.6 Completing the Installation

nOnce the baseplate and the batteries are installed, mount the

thermostat on the baseplate.

oSecure the thermostat using the locking screw and install the

faceplate.

pApply power back to the system.

3.1 System Operating Mode

Use the selector switch to place the system in Heating

mode (HEAT) or Cooling mode (COOL), or to turn the

system off.

Note: When you place the thermostat in Cooling mode, you might

need to wait up to five minutes before cooling can start. This is a

safety feature for the compressor. will flash on the screen until

cooling can start again.

3.2 Fan Operating Mode

Use the selector switch to set the fan to automatic

mode (AUTO) or continuous mode (ON).

Note: This switch is not used if you have a 2-wire

installation as the fan is not connected to the thermo-

stat.

3.3 Displaying the Temperature

The actual temperature is normally displayed. To view the setpoint,

press once on either of the buttons. The setpoint is displayed

for 5 seconds along with the icon.

Note: Pressing any of the buttons more than once will change

the setpoint.

3.4 Setting the Temperature

Press one of the buttons until the desired temperature is dis-

played.

3.5 Backlight

The display illuminates for 12 seconds when the backlight button or

either of the buttons is pressed.

3.6 Battery Replacement Indicator

An icon appears when the batteries need replacement.

This icon will flash for 120 days, then the thermostat

will cut power to the heating/cooling unit. The icon dis-

appears once the batteries are replaced. The tempera-

ture settings are saved and do not need to be re-entered.

Warning: Before removing the batteries, place the

system switch on the thermostat to Off. Otherwise, the

heating/cooling unit might still be running even after

the batteries are removed.

nTo access the configuration menu, press the backlight button

for 3 seconds.

oTo go to the next parameter (menu item), briefly press the back-

light button.

pTo modify a parameter, press .

qRepeat steps 2 and 3 if necessary.

rPress the backlight button for 3 seconds to exit the configura-

tion menu.

1 When either the heating or cooling parameter is displayed, use

the system mode selector switch to alternate between the two

parameters.

system as follows: 2=30 min (steam or gravity), 3=20 min (hot

water or 90%+ high-efficiency furnace),

4=15 min (gas or oil), 5=12 min (alternate setting for gas or oil),

6=10 min (electric).

3 The corresponding cooling cycle lengths are as follows: 2=30

min, 3=20 min, 4=15 min, 5=12 min, 6=10 min.
