Installation and Programming Guide

Programmable Low Voltage

Electronic Thermostat

As you are a valuable Ouellet Canada Inc. customer, we ask

that you please cut the power to the heating system from

the main power panel to avoid any risk of electric shocks.

OTH24-AFR

The 15-seconds cycle should only be used if an electronic

relay (SSR) activates the load

(Default: OFF).

Using a square or ﬂat screwdriver, loosen the screw a quar-

ter turn and separate the thermostat faceplate.

CONNECTING YOUR THERMOSTAT

Insert each wire into its terminal according to the heating

system and screw ﬁrmly. (See connection layouts outlined

below.)

4. In lock mode only:

Low temperature limit for heated ﬂoor only

(Default: 5 °C).

9. Minimum Time ON

Deﬁnes the minimum time for which the output can

be turned ON

Connection of the ﬂoor sensor (optional)

Used for gaz or oil system with a purge. The ON time

should not be shorter than the purge time.

0, 30 seconds, 1, 2, 3, 4, 5 minutes

(Default: 0).

MAIN CONFIGURATION MENU FOR INSTALLER

1. Press simultaneously the Menu button and the second-to-

last button (Next) and hold for 5 seconds to access the

installer settings.

2. Press Up or Down to change the setting displayed.

3. Press Next to go forward or Back to go back.

Programmable 7 days (7), Programmable 5/2 days (5/2), or

Non programmable (NP) (Default: 7 days).

ABOUT YOUR THERMOSTAT

The OTH24-AFR programmable low voltage electronic

thermostat is designed to control any 24-Vac heating load.

It has a terminal to connect a temperature sensor to read the

ﬂoor temperature. (Floor temperature sensor not included.)

0, 30 seconds, 1, 2, 3, 4, 5 minutes

(Default: 0).

The thermostat has two (2) low-voltage outputs that can

be connected using a 24-volt relay and a transformer to

control electric baseboard heaters, convectors (short cycle)

or forced-air convectors (long cycle), electric heating ﬂoors,

water pumps and boilers.

6. Thermostat control mode, choose between 3 modes:

A (Air) controls using the built-in air sensor of the

thermostat, F (Floor) controls using the optional ﬂoor sensor

and P (proportional) controls using a ﬁxed duty cycle

without using the temperature sensors.

electric baseboard on the 2nd heating stage

IMPORTANT: If the “Non programmable” interface is selected

in the installer settings, the time and programming schedule

menus will no longer be available.

The thermostat can run using a single output or two (2)

outputs. When two outputs are used, if the ﬁrst output

cannot control the heating system to reach the desired

setpoint, then the second output will be activated. This is

ideal for rooms where the ﬂoor is the main heating element

and a second heating element is used for colder days, like a

baseboard under the window.

(Default: A).

2. Keypad lock activation (Default: Oﬀ). If the keypad is not

locked, skip to Step 6.

Both outputs control cycle length can be conﬁgured separa-

tely. For example, the ﬂoor heating system could be on

a 15-minutes cycle using a mechanical relay and the base-

board would be on a 15-seconds cycle using an electronic

relay (SSR).

7. Main output cycle length

Select the cycle length according to the connected load

15 seconds, 5, 10, 15, 20, 25, 30 minutes.

The thermostat can also be used in proportional mode,

where it applies a ﬁxed duty cycle to its output.

Three (3) options possible:

• OFF: No lock.

Connection layout for a hot water valve

• INST: Installer menu locked, but all other functions are

accessible and the setpoint is limited by lock min/max.

• ALL: Keypad is fully locked.

The 15-seconds cycle should only be used if an electronic

relay (SSR) activates the load

(Default: 15 minutes).

Same programming for all modes

1. Press and hold Menu for 5 seconds to access user

settings.

2. Press Up or Down to change displayed setting.

3. Press Next to go forward or Back to go back.

IMPORTANT: When the lock option is activated, all thermostat

functions are deactivated except temperature adjustments

within the range allotted in the installer menu. The word

“LOCK” appears brieﬂy onscreen when a button is pressed.

In lock mode it is impossible to access the installer menu

without the 4-digit code.

4. Press Return

to exit the conﬁguration menu.

Note: The thermostat will automatically save all changes

and return to the regular display if no button is pressed

for 1 minute.
