Watts RCL-HC, User Manual

Page: 15 / 28

AUTOMATIC mode of operation
Automatic mode of operation using the built-in or user programs.
The ClimaticControl-HC is controlled according to the selected built-in or user program (
 6.2.).
The flow temperature is controlled depending on the outdoor temperature and the curve with room com-
pensation if RF thermostat is installed. (
 5.3.3 – 5.3.5).
 The room compensation function will be different depending of the RF thermostat installed:
* With WFHTRF-BASIC or LCD (Non programmable thermostat)
The room temperature compensation will be taken in account only during Comfort
period of the pro-
gram. During the Reduced period the Water temperature will follow the curve minus the temperature
setback offset.
* With MILUX RF (Programmable thermostat)
The room temperature compensation will be taken in account during Comfort
and Reduced period
of the program. In this case the program of the MILUX RF should be the same of the water program ad-
justed on the CC-HC to have the best optimising energy consumption (the water temperature will be re-
duced due to the CC-HC program (in ) and by the setting temperature reduced also in the room due to
the MILUX RF program.
* With MILUX-RF HYGROSTAT (Programmable Heat and Cool thermostat with Humidity supervising)
The program will be now done on the MILUX-RF HYGROSTAT (Program made on Zone1 see the user
guide of the MILUX-RF HYGROSTAT for more explanation).
The room temperature compensation will be taken in account during Comfort
and Reduced period
of the MILUX-RF HYGROSTAT program.
The Comfort and Reduced manual offsets added or subtracted to the calculated water temperature will be
always adjusted on the both working mode of the CC-HC (
0.00°C & -10.0°C by default).
 For the operation of the circulation pump please refer to the section of COMFORT mode of operation.
REDUCED TEMPERATURE mode of operation
Unlimited operation in REDUCED TEMPERATURE mode .
This is a constant mode of operation of the system. The ClimaticControl-HC adjusts the flow temperature
continuously on the basis of outdoor temperature and the selected curve and substracting the value of
temperature setback (factory setting -10.0 К in Heating mode & +3.0 К in Cooling mode).
The display indicates the current flow temperature at
5 and the outside temperature at 13 . By pressing the
button (OK) the preset value for the supply flow temperature reduced by the setback in temperature is
displayed at 5 for 3 seconds. Simultaneously the reducing difference appears in 13 (without deviation =
-10.0). It can be changed by the buttons (+) or (-).
 For the operation of the circulation pump please refer to the section of COMFORT mode of operation.
 See the previous part for more explanation concerning the room compensation function when RF
thermostat is installed.
ABSENCE/VACATION mode of operation
Time-limited operation of REDUCED TEMPERTURE mode .
Duration can be set between 1 and 24 hours and up to a maximum of 44 days. When this period is ex-
pired the ClimaticControl-HC switches back to operating mode
.
By means of the arrow keys (◄) the cursor is first moved to . Then appears on the display at 13 .
The duration of absence can be changed using buttons (+) or (-) .
Example: = 1 hour; = 1 day
Both symbols and start blinking. The remaining time is displayed at 13 .
To discontinue this mode of operation before time you have to set the remaining time at 13 to using
the (-) key.
