DEFINITION
Raises (+) or lowers (-) the slab regulating setpoint on
the rising edge of the input.
The setpoint is adjusted in whole degrees Fahrenheit or
Celsius, or half degrees Celsius if that option is selected.
Thus if the analog value of the slab setpoint equals 700
(for 70°), a rising edge of <Slab(min)Setpoint+> will
raise the slab setpoint value to 710 (for 71°). Similarly, if
the analog value of the slab setpoint equals 200 (for 20°)
and the half-degree Celsius option is selected, a rising
edge of <Slab(min)Setpoint-> will lower the setpoint
value to 195 (for 19.5°C).
Continuing to assert the up or down inputs at the limits
of each setpoint will not affect the setpoint. That is, the
setpoint will hold at its maximum or minimum setting.
High/1 (rising edge) = Slab setpoint up or down; Low/0 =
no effect
Turns the floor-warming system on or off on the rising
edge of the input.
High/1 (rising edge) = Turn floor-warming system
On/Off; Low/0 = no effect
Reports the status of the floor-warming system.
High/1 = Floor-warming system On/Off
Sets the slab regulating setpoint in tenths of a degree.
The scale (Fahrenheit or Celsius) is based on the
current setting in the unit.
The displayed setpoint value is rounded to whole
degrees Fahrenheit or Celsius, or half-degrees Celsius if
that option is enabled. This means that if the value 721
is presented on the slab setpoint input, the thermostat
LCD will display a slab setpoint of 72°. Similarly, if the
value 204 is presented on the slab setpoint input and the
half-degree Celsius option is enabled, the thermostat
LCD will display a slab setpoint of 20.5°.
Valid analog values range from 380 to 1210 (38° to
121°F); or 3 to 495 (3° to 49.5°C).
The setpoints will saturate in both directions. Thus
sending 0 will set the setpoint to its minimum value,
while sending 1300 will set the setpoint to its maximum
value.
Reports the slab regulating setpoint in tenths of a
degree. The scale (Fahrenheit or Celsius) is based on
the current setting in the unit.
Reports the temperature reading of any remote sensor
set to "Slab", in tenths of a degree. The scale
(Fahrenheit or Celsius) is based on the current setting in
the unit.
If more than one sensor is set to "Slab", this is the mean
slab temperature.
Sensors are set to Use, Omit, OD (Outdoor) or Slab via
the setup menus on the thermostat.
