Electronic Thermostat

Visual Overview

The thermostat front panel displays the current temperature (e.g., '21.0') and features temperature adjustment buttons. A visual indicator shows the percentage of heating time required, represented by SSSS symbols (e.g., 100% SSSSS, 75-99% SSSS, 50-74% SSSS, 25-49% SSSS, 1-24% SSSS). The asterisk (*) indicates that the thermostat displays the percentage of heating time required to maintain the desired temperature; for example, a specific symbol is shown when heating is activated 40 percent of the time.

Note: All cables and connections must conform to the local electrical code. Special CO/ALR solderless connectors must be used when connecting with aluminium conductors.

Wiring Diagrams

Two diagrams illustrate electrical connections. The '2-wire installation' shows a basic connection. The '4-wire installation' shows a more detailed setup.

1 Description

This thermostat is designed to control electric heating systems, including baseboard heaters, radiant ceilings, radiant floors, and convectors. It is not compatible with the following:

  • A resistive load under 2 A
  • A resistive load over 12.5 A
  • A system driven by a contactor or a relay (inductive load)
  • A fan-forced heating system (e.g.: fan-forced convector)
  • A central heating system

Supplied Parts

  • One (1) thermostat
  • Two (2) 6-32 mounting screws
  • Two (2) solderless connectors

2 Installation

TURN OFF POWER OF THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRIC SHOCK.

  1. Loosen the screw holding the control module to the base. The screw cannot be completely removed. Lift the control module to remove it from the base.
  2. Align and affix the base to the electrical box.

    Note: Before installing the thermostat base, install the provided adapter plate (U-shaped) on a 347V electrical box if it is larger than regular electrical boxes.

  3. Set the switch at the back of the removable part of the thermostat to °C or °F. A small switch on the back of the removable thermostat part allows selection between Celsius (°C) and Fahrenheit (°F).
  4. Make the appropriate connections. Please note that the thermostat wires are non-polarized; either wire can be connected to either terminal.
  5. Replace the front part of the thermostat on the base and secure it in place with the screw.

Note: Keep the air vents of the thermostat clean and unobstructed at all times.

3 Temperature Display and Setting

The thermostat normally displays the actual (ambient) temperature.

  • To view the setpoint temperature, press once on either temperature adjustment button. An icon appears during the setpoint display.
  • To change the setpoint temperature, press the appropriate button until the desired value is displayed.

4 Power Outage

During a power outage, the setpoint is saved in memory. The temperature setting does not need to be readjusted when power returns.

5 Specifications

  • Supply: 347 VAC, 50/60 Hz
  • Minimum load: 700 W / 2 A (resistive only)
  • Maximum load: 4335 W / 12.5 A (resistive only)
  • Display range: 0 °C to 50 °C (32 °F to 122 °F)
  • Setpoint range: 5 °C to 30 °C (40 °F to 85 °F)
  • Storage: -20 °C to 50 °C (-4 °F to 120 °F)

6 Troubleshooting

PROBLEM SOLUTIONS
Thermostat is hot. This is normal. Under normal operation, the thermostat housing can reach a temperature between 35 °C (95 °F) and 40 °C (104 °F).
Displayed temperature is wrong. Correct if any of the following conditions applies:
  • The thermostat is exposed to air draft.
  • The sticker on the thermostat's screen has not been removed.
  • The thermostat is located near or above a heat source such as a light dimmer.
Display disappears and reappears after a few minutes. The thermal protection device on the heater has temporarily opened. This can happen if the heater is obstructed by furniture or curtain and has overheated, or if the heater's thermal protection device is too sensitive.
Display looks faded when heating is activated. The heating system is less than the required minimum load. This thermostat cannot be used below that rating.
