Infloor TC 204 Heating Controller - Manual (Page 11)

Optimization
Menu 2
W.PR
OPT1 0 - 40 Default 20 Skip this line initially.
The colder it is outside and/or the further the room temperature is below set point the sooner the controller will
start the warm-up cycle. The number in this line is a constant in the equation the TC204 uses to calculate the
warm-up time. If the building warms up too soon, lower it to 15; if the building isnʼt warm soon enough, increase
this number to 25. If you set this line to 0 there is no warm-up cycle at all.
Calibration
Menu 12 CAL.
You can calibrate the temperature sensors used in the TC204.
R1 -9.5 to 9.5 degrees
Room Temperature Sensor Calibration
R2 -9.5 to 9.5 degrees
Second Room Temperature (if used)
OUTD -9.5 to 9.5 degrees
Outdoor Temperature Sensor Calibration.
SEC/D -9.9 to 9.9 seconds per day
If the clock runs fast or slow it can be adjusted here. If it is slow add a positive adjustment. If the clock gains one
minute per month, make the adjustment -2.0.
Daylight Savings Time
Menu 12 CAL
SUM Month 1 - 12 Day 1 - 31
Begin Daylight Savings Time. The first pair of digits is the month and the second is the day of the month.
The clock will move forward one hour at 2:00 am on the date you set.
WIN Month 1 - 12 Day 1 - 31
End Daylight Savings Time. Set it the same way as SUM above. If you donʼt want daylight savings time set both
SUM & WIN to 0000.
Time
Menu 12 CAL
24h 0 or 1 Default 0 (12 hour time)
Set this to 1 if you want 24 hour (military) time, 0 for 12 hour time. In 12 hour time P.M. shows as 3 dots between
the hours and minutes.
Temperature Scale
SEL.ºF 0 or 1 Default 1 (F)
Set this to 1 if you want readouts in Fahrenheit. Not all temperatures can be set or read in F.
O.RES 0 or 1
The readout of the minimum outdoor temperature can be reset manually or automatically. If you want the readout
to reset automatically every day set this line to 1.
Date Program
Menu 3 D.PRO
You can set up to 4 events that override the weekly program. These can be set up to a year in advance. You
can, for example, set a long term setback for a vacation.

Menu 4 X.OUT
There is an extra output that can be activated by either time or outdoor temperature or both.
Logging Measured Values
Menu 5 LOG
You can keep a log of up to 96 values of the outdoor temperature or the supply water temperature or the room
temperature at intervals up to 1 hour apart.
