Notes
You can change default 5-1-1 schedule here. To edit
periods, temperature setpoints during days, go to
MENU/PROG.
Floor Temperature Sensor needs to be wired to S
terminal and configured if you want thermostat to
operate either in AF or F mode (ISU 299). If Floor
Temperature Sensor is wired to S terminal and
configured, actual floor temperature can be displayed
in thermostat Menu/Temp.
This ISU configuration helps to optimize control
algoritms and to force optimal default cycle rates for
controlled heating euipment.
This ISU is only displayed if ISU 129 is configured for
1 (wired floor sensor) and ISU 205 is set to 10 (Hot
Water Radiant Floor Heat). Default Mode is AF.
AF Mode: Controls and displays the ambient air
temperature. Maintains the floor temperature within
desired limits using an external floor temperature
sensor.
A Mode: Controls and displays the ambient air
temperature only.
F Mode: Controls and displays the floor temperature
only using an external floor temperature sensor.
