The RTH2520 programmable thermostat can be used to control:

• 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

• 7-day programming including:

- Preprogrammed energy-saving schedule

- Early Start

- Temporary bypass

- Time display (12 h or 24 h)

• Filter replacement indicator

• Automatic daylight savings changeover

• Interchangeable faceplates (titanium, charcoal & taupe)

IN ORDER TO AVOID ANY RISK OF ELECTRIC SHOCK, CUT

POWER TO THE HEATING/COOLING SYSTEM.

nRemove the old thermostat to access the wires.

Warning: 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 thermostat.

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 in order to separate the thermostat

from its baseplate (the screw cannot be completely removed).

pGently tilt 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.

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.

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

The jumper specifies how the fan will operate

when it is placed in automatic mode (see sec-

tion 3.2).

nGently pull 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

sequence of tests for approximately 5 seconds.

Afterwards, the screen displays the actual

temperature. It is normal that the displayed

temperature be higher than the ambient

temperature if you are holding the thermo-

stat. Once installed on the wall, the thermostat will display the ambi-

ent temperature. By default, the setpoint is 70°F (21°C).

The time and day settings flash to indicate that they must be set

(see section 5.1).

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.

Use this selector switch to place the system in Heat-

ing mode (HEAT) or Cooling mode (COOL), or to set

both modes to 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 during

the delay.

Jumper

HG Leave the jumper in this position if you

have a gas or oil heating system.

HE Move the jumper to this position if you

have an electric heating system.

Use the selector switch to set the fan to automatic

mode (AUTO) or continuous mode (ON).

Note: This switch is not used in a 2-wire installation

as the fan is not connected to the thermostat in this

type of installation.

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

press once on one of the buttons. The setpoint is displayed for

5 seconds along with the icon.

Note: Pressing either of the buttons more than once will

change the setpoint.

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

played.

The display illuminates for 12 seconds when the backlight button or

either of the buttons is pressed.

Maintains the temperature at a fixed setpoint. To place the thermo-

stat in this mode, press [ Mode ]. The house icon will disappear.

Maintains the temperature according to the energy-saving sched-

ule. To place the thermostat in this mode, press [ Mode ]. The cur-

rent period will be displayed. The four possible periods are:

To see the default program settings, see section 5.3.

Temporary Bypass

If you modify the setpoint (using the buttons) when the thermo-

stat is in Programmable mode, the thermostat will use the new set-

point for the next 2 hours. The house icon flashes during the

bypass. Afterwards the thermostat will return to the temperature set-

ting of the period currently underway.

After 500 hours of operation, an icon appears to indi-

cate that the filter needs replacement. Once the filter

is replaced, press [ Filter ] for 3 seconds to remove

the icon and reset the counter.

Install fresh batteries immediately when the icon starts

flashing. The icon flashes for 120 days before the bat-

teries are depleted. You should replace batteries once

a year or before leaving home for more than a month

even if the icon has not appeared.

After replacing the batteries, set the time, day and date (see sec-

tions 5.1 and 5.2). However, the temperature and program 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.

nPress [ Clk ]. The hour flashes.

oSet the hour using .

pPress [ Clk ]. The minutes flash.

qSet the minutes using .

rPress [ Clk ]. The day flashes.

sSet the day using . (MO: Monday, TU: Tuesday,

WE: Wednesday, TH: Thursday, FR: Friday, SA: Saturday and

SU: Sunday).

tPress [ Exit ] to exit.

The date is needed for automatic daylight savings changeover.

nPress [ Clk ] for 3 seconds to display the year.

AUTO The fan operates only when the heating or cooling sys-

tem is On (typical setting).

ON The fan operates continuously. Use this setting to

improve air circulation and air cleaning.

1 When Early Start is On, the thermostat determines when to start heating or cooling

so that the desired temperature is reached at the set time.

2 When this function is On, the thermostat automatically switches to daylight savings

time on the second Sunday of March and to normal time on the first Sunday of

November (see section 5.2).

3 Use the Heat/Cool selector switch to switch between the heating parameter and the

cooling parameter.

4 For optimal heating control, use the setting that matches your system as follows:

2=30 min (steam, gravity), 3=20 min (hot water, 90%+ high-efficiency furnace), 4=15

min (gas or oil), 5=12 min (alternate setting for gas or oil), 6=10 min (electric).

5 The corresponding cooling cycle lengths are: 2=30 min., 3=20 min., 4=15 min.,

5=12 min., 6=10 min.
