Option 2: Selecting the Heat Cycle Rate
To provide precise, consistent and economical heating, this thermostat has an adjustable heat
cycle rate. The cycle rate determines the on/off time cycles that the thermostat uses to reach
and maintain the desired temperature.
Certain cycle rates are more efficient when used with certain types of electric heating systems.
Selecting the correct cycle rates help maintain an even temperature, which has been proven
to reduce energy usage while improving comfort.

will be turned on and off once every 20 seconds to provide a stable room temperature.
The cycle rate allows a proportional level of power to the heating device. This is indicated
on the thermostat display by the power bar which will be partially filled; indicating the
amount of power going on the heater. This setting is recommended for non-fan assisted
baseboards and electric heating devices

This thermostat is equipped with a Pre-comfort Recovery feature which activates the
heating system in advance of the actual set program time so that the room will be at the
desired temperature at the start of the program time.
It is normal for the system to be activated earlier than the actual set program time (up to
an hour). The Pre-comfort Recovery feature can be disabled, if desired. If this feature is
turned off, heating will only be initiated at the exact start time of the program period.

Celsius (⁰C) is the default temperature unit; no action is required if this is the desired
temperature display.
IMPORTANT: If you wish to use Fahrenheit (⁰F), it is important to choose this
temperature unit before you begin programming the thermostat. If you proceed to
set programs using the default mode in Celsius (⁰C), then change to Fahrenheit (⁰F)
or vice versa, all programs set by the user will be deleted and will reset to factory
defaults.

Program Periods
For maximum energy savings, this thermostat is equipped with 7-day programming –
you can program 4 settings per day for each day of the week. This thermostat is pre-
programmed for your convenience, or you can set your own programs as desired.
The program periods (P1, P2, P3 and P4) allow you to set the temperature settings
and start times throughout the day.
During the morning, when you may prefer to wake up to a warmer
temperature.
The time you leave home is usually an energy-savings period; when
the temperature can be reduced to minimize energy consumption.
If you are staying home on a particular day, you may override this
setting by manually adjusting the temperature using the
button.
This the time you return home when you prefer to set the
temperature to a comfortable level. Generally, the temperature is set
to warmer settings during fall/winter and to cooler settings during
spring/summer. If you stay home during the day, periods 1, 2 and 3
can be set at the same temperature level.
This is the time you go to bed, also an energy savings period. You
may set the temperature to your desired energy saving level to save
on heating cost.

Troubleshooting
Problem Solution
The LCD screen is blank or
abnormal
• Make sure the thermostat is fully installed.
Check that the power supply has been reconnected at
the circuit breaker or fuse.
If the heater or heating appliance has a power switch
of its own, check to see that it is in the ON position.

•
The thermostat housing feels
hot to the touch
When working at full capacity, the thermostat
housing may reach a temperature of approx. 45°C
to 50°C (113°F to 122°F). This is normal and does
not affect the operation of the thermostat.
The thermostat is rated to operate safely at these
temperatures; ensure that the thermostat is not near
heat sensitive or flammable materials such as exposed
wood or wallpaper.
The heating system is constantly
running
Make sure the temperature is not set too high.
The heating system seems to cycle
too often
Make sure the selected cycle matches the heating
system (see pages 7 and 8 for details).

• Review the programming guide to ensure the programs
have been entered correctly.
Check that the clock has been set to the correct time
(e.g. AM and PM are reversed).
Reset programs: Press SET for 3 seconds to enter
option mode, then press PROG for 3 seconds to clear
program settings only.
•
•
• Reset all: Press and hold the and buttons
at the same time to restore all settings to factory
defaults.
HOLD RESET
The heating system will not
activate
Temperature settings will not
change
Make sure the temperature is set to the acceptable
range: 5°C to 35°C (41°F to 95°F).
• Check the LCD display to see if there has been a power
failure.
If the symbol appears on the LCD screen when
you increase the temperature, the High Limit Function
is activated. (To deactivate, see page 18 for details.)
Check the heating device to see if it is disabled or if the
circuit breaker is open.
