Aube TH232-AF-230 Programmable Thermostat
Parts
- One (1) thermostat
- One (1) floor sensor
- One (1) wall plate
Guidelines
Turn off power to the heating system at the main power panel to avoid electrical shock. Installation should be carried out by an electrician.
- All work must conform to the applicable country standards for electrical installations and wiring.
- This thermostat should be connected on a circuit equipped with a fuse or a circuit breaker. It must be installed on a certified electrical box equipped with non-metallic cable strain relief adapters. Use separate adapters for the high-voltage wires and for the sensor cable.
- For a new installation, choose a location about 1.5 m above the floor.
- For electric baseboards, convectors and fan-forced heaters, the thermostat must be installed facing the heating system and on an inside wall.
- Avoid locations where there are air drafts (top of staircase, air outlet), dead air spots (behind a door), direct sunlight or concealed chimneys or stove pipes.
NOTE: The terminals are designed to handle a cross-section of wire measuring 0.33 to 3.1 mm2.
Procedure
- Loosen the captive screw underneath the base and remove the faceplate from the base.
- Before making the connections, make sure that the base covers the electrical box entirely. If not, install a wall plate at the back of the base
- Connect the wires:
- Power: Terminals 1 & 5
- Load: Terminals 2 & 4 see note 1
- Pilot Wire: Terminal 3 see note 2
- Floor sensor: Terminals 6 & 7 (no polarity)
WARNING: Ensure that the wires are tightly secured to the terminals.
Apply a minimum torque of 0.5 Nm (4.4 Lb/in) when tightening the screws.
Note 1 If a contactor is used between the thermostat and the load, install a snubber at the contactor’s coil terminal to ensure the proper operation of the thermostat.
Note 2 This connection is required on some models only.
Note 3 The sensor cable must pass outside the electrical box and travel inside the wall to the floor. For the proper operation of the thermostat, the floor sensor must be centered between two heater wires having a maximum temperature of 80 °C (176 °F). The floor sensor wire must not cross any heater wire or be placed close to it.
- Push wires into the electrical box and secure the base to the electrical box anchorage. The head of the screw must be less than 2 mm thick.
- Return the faceplate to the base.
- Return power to the heating system.
NOTE: Keep the thermostat’s air vents clean and unobstructed at all times.
Operating Instructions
Programmable Thermostat
Description
This thermostat provides the following temperature control modes:
- A mode: controls and displays the ambient air temperature
- F mode: controls and displays the floor temperature using an external temperature sensor (default mode)
- AF mode: controls and displays the ambient air temperature and maintains the floor temperature within desired limits using an external temperature sensor.
Use this button to disable heating (e.g. in the summer). The thermostat remains powered and continues to display the time and temperature.
Power Up
Apply power to the thermostat at the main electrical panel. At power-up, the thermostat is in manual mode and displays the actual (measured) temperature. The setpoint temperature is 28 °C (82 °F)
Error Messages
- LO The actual temperature is below 0 °C (32 °F).
- HI The actual temperature is above 70 °C (158 °F).
- Er The thermostat built-in sensor is defective. Replace the thermostat.
- E1 The floor sensor circuit is opened. Check the sensor connections.
- E2 The floor sensor circuit is shorted. Replace the sensor.
Configuration
Control Mode Selection
- Press and hold the Clear button for 3 seconds. The current control mode is displayed (ctl).
- Press the to select between A, AF and F.
NOTE: If you have chosen the A or F mode, go to step 7. If you have chosen the AF mode, the thermostat will control the ambient temperature while keeping the floor temperature within desired limits. If the floor temperature is too low or too high, the thermostat will turn heating on or off to maintain the floor temperature within the limits regardless of the ambient temperature. The minimum and maximum floor temperature limits are factory-set at 5 °C (41 °F) and 28 °C (82 °F) respectively.
To modify the limits, continue with the next step: - Press the Clear button briefly. The minimum limit is displayed (FL:LO).
- Press the button to set the minimum limit.
- Press the Clear button briefly. The maximum limit is displayed (FL:HI).
- Press the buttons to set the maximum limit.
- Press the Mode/Return button to exit and save the changes.
NOTE: If no button is pressed for 60 seconds, the thermostat will save the changes and return to the normal display.
Other Configurations
This procedure allows you to choose the following configurations:
| Parameters | Default settings |
