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).

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).

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).

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.

Ouellet Canada OTH24-AFR Programmable Low Voltage Electronic Thermostat User Guide Overview

Summary of Contents

• Page 1: output cycle length Select the cycle length according to the connected load. If lock mode is activated, you will need to enter a 4-digit code. Cut the power to the heating system from the main power panel to avoid any risk of electric shocks. The 15-seconds cycle should only be used if an electronic relay (SSR) activates the load. Insert each wire into its terminal according to the heating system and screw firmly. Minimum time ON defines the minimum time for which the output can be turned ON. User interface selection: Programmable 7 days, Programmable 5/2 days, or Non-programmable. The OTH24-AFR programmable low voltage electronic thermostat is designed to control any 24-Vac heating load. The thermostat has two low-voltage outputs that can be connected using a 24-volt relay and a transformer. IMPORTANT: When the lock option is activated, all thermostat functions are deactivated except temperature adjustments.
• Page 2: Floor temperature limit maximum: 5 °C to 36 °C (Default: OFF). Floor temperature limit minimum: 5 °C to 36 °C (Default: OFF). In the event of a power failure, the screen will turn off and your settings will be saved. If the power failure exceeds 8 hours, you will have to reset the time and date. A floor sensor must be installed to access the minimum and maximum floor temperature limits. Error codes indicate various issues with the thermostat temperature sensors. The thermostat features two different programming methods: 5-2 and 7. The Boost mode is only available in Ambient mode and proportional mode. The manufacturer warrants the components of the product against defects for a three-year period. If no heating is required, you can put the thermostat in Sleep mode.
