OTH24-AFR

Low Voltage Non Programmable Electronic

Thermostat (2 outputs)

Low Voltage Programmable Electronic

Thermostat (2 outputs)

Features

Type

• Low voltage electronic thermostat.

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).

Color

• Standard: white.

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.

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 tempera-

ture 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):

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

The second output is activated if the first heating system controlled

by the first output cannot reach the temperature setpoint.

• 2 low voltage outputs that can be connected using a 24V relay and

a transformer to control electric baseboard heaters, convectors,

forced-air convectors, electric heating ﬂoors, water pumps and boilers.

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

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

Warranty

• 3-year warranty against defects.

OTH24-AFR Features

Configuration

Program

• 4 programming modes:

• No freeze: The thermostat maintains a temperature setpoint

of 5 °C (41 °F).

• "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.

• 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).

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).
