4. Additional Setups
Air Sensing and Regulator Modes
Your thermostat is factory set to operate based on the floor sensor
temperature. This is the recommended method to properly control your floor
warming system.
However, it is also possible to operate your thermostat in either the air sensing
mode or regulator mode temporarily if the floor sensor was damaged or not
installed. A new floor sensor should be installed to enable operation in Floor
Sense Mode as soon as possible. These modes must be used with caution to
avoid overheating the floor.
• Air Sensing Mode – This operates by an air sensor inside the thermostat.
You must set a Floor Limit temperature to avoid overheating the floor coverings
(see
Floor Limit
below).
Note:
the internal heating in the thermostat may
affect the sensor temperature.
• Regulator Mode– In this mode the user selects the amount of time the
floor warming system heats during a 15-minute repeating cycle. There is no
temperature sensing in this mode. (see section 5
“
Operation
”)
If you want it to operate in the air sensing mode or regulator mode, you may
change this as follows:
1.
Press the OPTIONS button and hold for 1 second.
2.
Press the OPTIONS button again until
SENS
shows on the
display.
3.
Press the down or up button to toggle this to
Air
or
rEGu
.
4.
Press the HOLD/RETURN button to return to the normal
operating mode.
Floor Limit
If you set your thermostat to operate in Air Sense Mode, the display will show
the air temperature but will also monitor the floor sensor if it is connected.
To avoid possibly overheating your floor, you must set a Floor Limit temperature
so it turns off the system if the floor sensor temperature exceeds this Floor
Limit. Some wood and laminate floor manufacturers recommend a maximum
of 82 to 84°F (27° to 28°C). Check with manufacturer. It is factory set to 99F
(37C) and can be adjusted as follows:
1.
Press the OPTIONS button and hold for 1 second.
2.
Press the OPTIONS button again until
SET TEMP
and
FLOOR
LIMIT
shows on the display with the current Floor Limit temperature.
3.
Press the down or up button to adjust this.
4.
Press the HOLD/RETURN button to return to the normal operating
mode.

Resetting Factory Defaults
Your thermostat has the ability to reset all settings to the factory defaults. If
you are certain you want to do this:
1.
Press the OPTIONS button and hold for 1 second.
2.
Press the OPTIONS button again until the software version
Soft 1.0
or similar shows on the display.
3.
Press the down and up buttons at the same time and hold
for 1 second.
Done
and
rst
will show on the display. The
thermostat will go through a startup mode and return to the
normal operating mode.
5. Operation
Controlling the Temperature
Your thermostat has several ways to control your floor warming system.
Adjust the Temperature
1.
Press the down or up button and hold for 1 second. The setpoint
temperature should be blinking.
2.
Press the down or up button again to adjust the temperature.
3.
Press the HOLD/RETURN button or wait 5 seconds and the thermostat will
return to the normal operating mode, saving your adjustment.
Setback
You can use the Setback button to override the current setpoint temperature.
This is especially useful if you have an alternate temperature you repeatedly
select when you are away.
1.
Press the SETBACK button briefly.
SETBACK
will show on the
display and its temperature.
2.
To cancel this Setback temperature and return to the normal
temperature, press the SETBACK button briefly.
To change the temperature stored in the SETBACK button:
1.
Press the SETBACK button and hold for 1 second.
SETBACK
will show on
the display and its temperature should be blinking.
2.
Press the down or up button to adjust the temperature.
3.
Press the HOLD/RETURN button or wait 5 seconds and the thermostat will
return to the normal operating mode, saving your adjustment.
Remote Control Override
If your thermostat was installed with Remote Control input from a home
automation system (see section 2
“
Installation
”), this will override the
thermostat when the remote control system closes its output switch or relay.
SETBACK
will show on the display and it will operate in the Setback
temperature indefinitely. To cancel this, the Remote Control switch or relay
must be opened.
Regulator Mode
If you set your thermostat to operate in the regulator mode, it will operate like
a timer. You may adjust the amount of time the floor warming system heats
during a 15-minute repeating cycle as follows:
1.
With the thermostat in the regulator mode, it will show the
heating time and the current cycle time.
2.
Press the down or up button to adjust the heating time from 0
through 15.
• Example: A value of 6 will cause it to heat for 6 minutes of
the 15 minute cycle, and then not heat for 9 minutes of the 15
minute cycle.
• Zero will cause it to never heat.
• 15 will cause it to heat continuously.
3.
The cycle time shown at the bottom of the display is the current time in the
15-minute cycle. It repeats from 0:00 through 14:59 (min:sec).
