Aube Technologies OTH800D Nonprogrammable Thermostat

OVERVIEW

Description

This programmable thermostat can be used to control an electric heating system such as an electric baseboard heater, a radiant ceiling, a radiant floor, a convector, etc. The thermostat cannot be used with the following:

• a resistive load greater than 16.7 A
• a resistive load less than 2 A
• a system is driven by a contactor or relay (inductive load)
• a central heating system

SUPPLIED PARTS:

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

Installation

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

• All cables and connections must conform to the local electrical code.
• Special CO/ALR solderless connectors must be used when connecting with aluminum conductors.
• Install the thermostat onto an electrical box.
• Install the thermostat about 5 feet high, on an inside wall facing the heater.
• Avoid locations where there are air drafts (such as the top of a staircase or an air outlet), dead air spots (such as behind a door), or direct sunlight.
• Do not install the thermostat on a wall that conceals chimneys or stove pipes.
• The thermostat wires are not polarized; either wire can be connected to the load or to the power supply.

NOTE: Always keep the thermostat’s vents clean and unobstructed. THE INSTALLATION MUST BE PERFORMED BY AN ELECTRICIAN.

1. Connect the thermostat wires to the line wires and to the load wires using solderless connectors for copper wires.
2. 2-wire installation
3. 2-wire installation
4. Push any excess wire back into the electrical box.
5. Before installing the TH106 thermostat base, install provided adapter plate (U-shaped) on the 347V electrical box which is bigger than regular electrical boxes.
6. NOTE: If necessary, before re-installing the front component, configure the thermostat (see section 3).  Return power to the heating system.

Configuration

The configuration switches are on the back of the thermostat. The factory settings are indicated by the gray cells in the following table.

SW1	Early Start a	Off	On
SW2	Temperature/time format b	°C / 24-hour	°F / 12-hour
SW3	Cycle length c	15 seconds	15 minutes
SW4	Not used	–	–

• Early Start can be used in Automatic mode only. When this function is enabled, the thermostat calculates the optimal time to start heating in order to obtain the desired temperature by the set time. The thermostat re-assesses the start time daily based on the previous
• If you change the temperature display format, the preset temperatures ( and ) will return to their default settings
• 15-second cycles should be selected in most cases as it provides better temperature control. 15-minute cycles must be selected if you have a fan-equipped heater or if 15-second cycles cause light flickering (especially in rural regions).

Power-up
Upon power-up, the thermostat is in manual mode ( ) and displays the actual (ambient) temperature.

• Press the Hour and Min buttons to set the thermostat’s clock.
• Press the Day button to set the day.

Temperature Setting

Setpoint
The thermostat normally displays the actual temperature. To view the setpoint, press the or button briefly. The setpoint will appear for the next 5 seconds. To change the setpoint, press the or button until the desired temperature is displayed. To scroll faster, hold the button. Using a preset temperature

The thermostat has 3 preset temperatures

• To use the Comfort or Economy temperature, press the or button respectively. The corresponding icon will be displayed.
• To use the Vacation temperature, press both buttons simultaneously. The icon will be displayed.

Storing a preset temperature
To store the Comfort or Economy temperature:
Set the desired temperature using the or button. Press and hold the appropriate button ( or ) for approximately 3 seconds until the corresponding icon is displayed.

• To store the Vacation temperature:
• Set the desired temperature using the or button. Press and hold both and buttons simultaneously for approximately 3 seconds until the icon is displayed.

Operating Modes

Automatic – The temperature is set according to the programmed schedule. To place the thermostat in this mode, press Mode until is displayed. The icons of the current period and preset temperature are also displayed.

Temporary Bypass: If you modify the setpoint (by pressing the or button) when the thermostat is in automatic mode, the new setpoint will be used until the end of the current period. When the next period starts, the temperature set for that period becomes the new setpoint.

Manual – The programmed schedule is not used. The temperature must be set manually. To place the thermostat in this mode:

• Press Mode until is displayed.
• Set the temperature using the or button.

Schedule

The schedule consists of 4 periods per day which represents a typical weekday. You can program the thermostat to skip the periods that do not apply to your situation. For example, you can skip periods 2 and 3 for the weekend

The Comfort ( ) temperature is used in periods 1 and 3 and the Economy ( ) temperature is used in periods 2 and 4. For example, when the period changes from 1 to 2, the setpoint automatically changes from Comfort setting ( ) to Economy setting ( ). You can have a different program for each day of the week; i.e., each period can start at a different time for each day of the week. The thermostat has been programmed with the following schedule

To modify the schedule

• Press Pgm to access the programming mode. Period 1 is selected.
• Press Day to select the day to program (hold for 3 seconds to select the entire week).
• Press Hour and Min to set the start time of the selected period, or press Clear if you want to skip the period (–:– is displayed).
• Press Pgm to select another period, or press Day to select another day. Then repeat step 3.
• Press Mode to exit the programming mode.
  NOTE: If no button is pressed for 60 seconds

Power Outage

During a power outage, the settings are stored in memory. However, only the thermostat’s clock must be re-adjusted if the power failure lasts more than 2 hours. When the power comes back, the thermostat will return to the operating mode that was active prior to the power failure.

Troubleshooting

PROBLEM	SOLUTIONS
Thermostat is hot.	This condition is normal. Under normal operation, the thermostat housing can reach a temperature between 35°C (95°F) and 40°C (104°F).
Wrong temperature is displayed.	The thermostat is exposed to air draft. Eliminate the draft. The sticker on the thermostat’s screen has not been removed.
Wrong time is displayed.	The thermostat was without power for more than 2 hours.
Temperature does not change according to the programmed schedule.	Check that the thermostat is in Automatic mode. Check the schedule and clock set- tings.
Display disappears and reappears after a few minutes.	The thermal protection device on the heater is open. This can happen after a power failure or if the heater is obstructed by furniture or curtains.
Display looks faded when heating is acti- vated	The heating system is less than the required minimum load. This thermostat cannot be used below that rating.
