Ouellet OTH24 Low Voltage Programmable Electronic Thermostat Product Specification Guide

Ouellet OTH24 Low Voltage Programmable Electronic Thermostat 

Features

Type
Low voltage electronic thermostat.
Color
Standard: white.

Voltage
24Vac, 50/60 Hz.

Power
1A per output (2 outputs).

Mode

•  First output (main):
• A mode: Ambient temperature control.

Note: Floor temperature can be controlled using an external temperature sensor when a floor heating cable is used as the heating source.

• F mode: Floor temperature control using an external temperature sensor with ability to control the ambient temperature.

Second output (auxiliary):

• The second output is activated if the first heating system controlled by the first output cannot reach the temperature setpoint.

Control

• 15-second cycle or 5, 10, 15, 20, 25, 30-minute cycle (individually adjustable on each output).
• Adjustment of the minimum Time ON and minimum Time OFF on the main output. Defines the minimum time for which the output can be turned ON or turned OFF (used for heating system with a purge).
• Pump exercise OFF/ON (if set to ON, the thermostat activates its main output for 1 minute every 24 hours to prevent pump from seizing).
• Resolution: 0.5 °C (1 °F).

Display

•  Digital display of ambient temperature (°C or °F), heating level indicator and temperature setpoint.
•  Backlit – permanent or activated on request.
•  Temperature setting recorded permanently.

Temperature range
5 °C to 36 °C (41 °F to 97 °F).

Storage Temperature
-20 °C to 50 °C (-4 °F to 158 °F).

Installation
3-wire thermostat (minimum).

Application
2 low voltage outputs that can be connected using a 24V relay and a transformer to control electric baseboard heaters, connectors, forced-air convectors, electric heating floors, water pumps and boilers.

Note: Select the cycle according to the type of heating.

Warranty
3-year warranty against defects.

OTH24-AFR Features

Configuration
“Installer” configuration menu used to lock certain thermostat functions with a 4-digit code. Ideal for restricting access to programming functions or to the temperature setpoint.

Mode

• First output (main):
• P mode: Proportional control with fixed cycle rate. This mode works without using a temperature sensor (ideal for controlling radiant heating units).
• “Boost” (timer) function on the auxiliary output (only available in Ambient or Proportional mode).

Program

• 4 programming modes:
• No freeze: The thermostat maintains a temperature setpoint of 5 °C (41 °F).
• Manual: All settings must be adjusted manually.
• Automatic: The thermostat automatically changes the temperature settings according to the programmed settings:
• “5-2”: One program for weekdays and one for the weekend.
• “7”: A different program for every day of the week.
• Off (Sleep mode).
