Programmable Thermostat

Description

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

• a resistive load under 2 A
• a resistive load over 14.6 A
• systems are driven by a contactor or relay (inductive load)
• central heating systems

SUPPLIED PARTS

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

Installation

TURN OFF 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 a chimney or stovepipes.
• The thermostat wires are not polarized; either wire can be connected to the load or to the power supply.

1. Connect the thermostat
   Connect the thermostat wires to the power and to the load using solderless connectors for copper wires.
   
2. Mount the thermostat
   Push the excess wires back inside the electrical box.
   Secure the thermostat to the electrical box using the provided screws.
   Insert the screws through either the right or left pair of mounting holes on the thermostat.
   
3. Complete the installation
   Peel the sticker off the display.
   Keep the thermostat’s air vents clean and free from obstructions.
   Apply power to the heating system.
   

Temperature Display and Setting

The thermostat normally displays the actual (ambient) temperature.

• To view the setpoint, press once on either of the temperature adjustment buttons.
• To change the setpoint, press the appropriate button until the desired setpoint is displayed.

Configuration

The factory settings are indicated by the gray cells in the following table.

Warning: Every time you reconfigure the thermostat, you must readjust its clock and reprogram the schedule.

Temperature display
To change the temperature display between °C and °F:

1. Press and hold.
2. Insert a pointed object (e.g., paperclip) through the reset opening.
3. Wait one second and release.

Time display
To switch between the 12-hour format and the 24-hour format:

1. Press and hold.
2. Insert a pointed object (e.g., paperclip) through the reset
   opening.
3. Wait one second and release.

Temperature control

• Proportional control should be selected in most cases as it provides better temperature control.
• Conventional control must be selected if you have a fan-equipped heater or if proportional control causes light flickering (especially in rural regions).

The FAN indicator is displayed when conventional control is selected. To switch between the two types of control:

1. Press and hold.
2. Reset the thermostat using a pointed object (e.g., paperclip).
3. Wait one second and release.

Clock and Day Setting

The clock must be set when TIME flashes on the screen.

1. Press to set the day.
2. Use and to set the clock.
3. Press to exit.

Modes of Operation

The thermostat has three modes of operation:
Automatic (programmable) mode

To use the Automatic mode, press the mode selection until AUTO is selected on the screen. The number of the current period will appear.
Use this mode when you want the thermostat to use the settings programmed into the schedule.
The schedule has 4 periods in a day. During each period, the thermostat uses the temperature that has been set for that period. The same program is used daily from Monday to Friday and another program is used for Saturday and Sunday.

The following schedule is pre-programmed into the thermostat:
NOTE: The schedule must be reprogrammed every time you alter the thermostat’s configuration.

To temporarily override the current setpoint, set the desired temperature using the temperature adjustment buttons. The new setpoint be used until the beginning of the next
period.

To program the schedule:

1) Press the mode selection button until AUTO is selected.
2) Press.

Each time you press, the thermostat scrolls through the periods of the schedule in the following order (from left to right):

3) Set the start time for the displayed period using and. To skip a period, do not set the start time for that period.

NOTE: To reset a period, press the mode selection button.
4) Set the temperature for the period using the temperature adjustment buttons.
5) Repeat steps 2 to 4 for the remaining periods.
6) Press to return the thermostat to normal operation.

Manual (hold) mode
To use this mode, press the mode selection button until MAN is selected on the screen and set the desired temperature using the temperature adjustment buttons. In Manual mode, the programmed schedule is not used. The temperature must be set manually.

Economy mode
To use the Economy mode, press the mode selection button until ECONO is selected on the screen. The Economy mode is ideal for weekend residences and is to be used only when you are not there. In this mode, the thermostat provides two temperature settings which can be used as follows:

• Setting 1 can be used to raise the temperature to a comfortable level by your expected arrival time.
• Setting 2 can be used to lower the temperature if you do not show up by the usual time.

A typical schedule is shown below.

The Economy mode can be used as follows:

• Place the thermostat in Economy mode when you are away from your cottage.
• Upon your arrival, switch the thermostat to Automatic mode or Manual mode before setting 2 of the Economy mode starts.
• When departing, switch it back to Economy mode. The thermostat will then lower temperature (setting 2) during most of your absence and will raise temperature prior to
  your expected arrival (setting 1).

To enter the two temperature settings:

1. Press the mode selection button until ECONO is selected.
2. Press. The first period is displayed.
   
3. Set the start day for the displayed period using.
4. Set the start time using and.
5. Set the temperature for the period using the temperature adjustment buttons.
6. Press to select the next program (2).
7. Repeat steps 2 to 4 to set the day, time, and temperature.
8. Pressto returns the thermostat to normal operation.

Thermostat Reset

Warning: After the thermostat is reset, you must re-adjust its clock and reprogram the schedule. You might need to set the thermostat’s configuration.

1. Press and hold.
2. Reset the thermostat using a pointed object (e.g., paperclip).
3. Wait one second and release.

Power Outage

During a power outage, the thermostat display remains lit for approximately the next 15 minutes during which the low power (LP) indicator appears. The settings are stored in memory. However, if
the power failure exceeds 5 hours, only the thermostat’s clock must be re-adjusted. When power returns, the thermostat returns to the mode of operation preceding the power outage.
