Base Data Register Offset
Register Offset Register Function
0 Tempering Set Point
The tempering set point determines the temperature that the floor tempering will operate
at. This value is compared with the floor temperature input to determine if cooling or
heating is required and the direction of the fan.
1 Floor Temperature Hysterisis Setting
The floor temperature hysterisis value is subtracted from the floor temperature set point
to allow the floor tempering to drive slightly above and below the set point.
2 Duct Temperature Set Point
This sets the maximum value for the duct sensor and is used to control the heating of the
duct air.
3 Duct Temperature Hysterisis Setting
The duct temperature heating hysterisis value is added to the duct heating set point to
allow the floor tempering to drive slightly beyond the set point. This setting prevents the
floor tempering system from oscillating between the dead band and heating modes.
4 Current Floor Tempering Mode
The current mode that the floor tempering is operating in. The floor tempering modes are
listed in the section below.
Floor Tempering Mode Definition
Register Offset Register Function
0 Floor Tempering Idle Condition
The programmable function is idle and no processing is taking place.
1 Floor Tempering Waiting For Start Signal
The programmable function is waiting for the enable PGM signal to be controlled to an
ON state to start operation. This is usually managed by a schedule or the alarm status.
When the signal is received the Fan PGM will be activated and the programmable
function will enter a delay of 30 seconds before starting.
2 Floor Tempering Waiting Check
If the floor tempering is checking if it requires to operate in a manual or automatic mode.
3 Floor Tempering Dead Band Process
The dead band process is where the floor tempering will wait for a condition that is
outside the set point for tempering of the floor or heating the duct.
4 Floor Heating
The floor temperature is below the floor heating set point and the function to start the
heating process is active. This will activate the floor heater that is required to bring the
temperature up to the heating set point.
5 Floor Cooling
The floor temperature is above the floor heating set point and the function to start the
cooling process is active. This will operate the floor tempering in reverse and disable the
duct heater.
6 Manual Heating Forward
The manual forward (heating) override PGM is active and the floor tempering is operating
in Manual Heating mode.
