o
“
CH
” - selected if the user wants to control CH chain temperature.
o
“
FLOOR
” - selected if the user wants to control the temperature of underfloor heating chain. It protects the
underfloor heating equipment from hazardous temperature. If the user chooses CH as the type of valve and
connects it with the underfloor heating system, it can damage the fragile floor equipment.
VI.c.6)
Room regulator
This function allows the user to select and to set the room regulator operation that controls the valve.
o
Control without room regulator
This option must be chosen if the user does not want the room regulator to influence the operation of the valve.
RS regulator - reduction
This option must be selected if the valve is controlled with room regulator with RS interface by reducing the pre-set
temperature with advance value. In case of selection of this function, the menu shows option:
“Room reg. temp
lower”
o
RS regulator - proportional
When this type of room regulator is selected, the valve is controlled according to
Change of pre-set valve temp.
and
Room temperature difference parameters
(these parameters are shown in menu when this preparation is selected). By
activating this room temperature regulator, you can monitor the current temperature of CH boiler, water tank and
valves. The regulator must be connected to ST-650 controller RJ (telephone) socket by using 4-strand cable with
respective plugs (RS socket).
o
TECH standard regulator
This option is selected if the valve is controlled by room regulator with RS interface. Regulator functions according
to the parameter set by
Room reg. temp lower
.
o
Standard valve regulator
This option should be selected if the valve is controlled by the room regulator of two conditions (without RS
interface).
o
Room reg. temperature lower
This function is activated only if TECH standard regulator or standard valve regulator is selected. The user defines
the valve temperature reduction value which is reduced when the room regulator reaches the pre-set temperature.
o
Room temperature difference
Note
These parameters are related to RS regulator - proportional.
This setting is used to define the single change in the current room temperature (the precision is 0.1°C), when the
pre-set valve temperature is changed (the function is accessed only by TECH room regulator with RS interface).
For example:
Setting: room temperature 0.5ºC difference setting: change the pre-set valve temperature by 1ºC
