Example: Val
ve preset temperature: 50°C
Hysteresis: 2°C
Valve stop: 50°C
Valve opening: 48°C
Valve closing: 52°C
When the set temperature is 50°C and the hysteresis is 2°C, the valve will stop in one position when the temperature
reaches 50°C, when the temperature drops to 48°C
,
it will start to open and when it reaches 52°C
, the valve will start
to close in order to lower the temperature.
➢
Valve type
–
This option enables the user to select the following valve types:
•
CH valve
- set when we wish to control the temperature in the CH circuit using the valve sensor. The valve sensor
shall be placed downstream of the mixing valve on the supply pipe.
•
Floor valve
- set when we wish to adjust the temperature on the underfloor heating circuit. The floor type protects
the floor system against excessive temperatures. If the type of valve is set as CH and it is connected to the floor
system, it may lead to damage to the floor system.
•
Return protection
- set when we wish to adjust the temperature at the return of our installation using the return
sensor. Only return and boiler sensors are active in this type of valve, and the valve sensor is not connected to the
controller. In this configuration, the valve protects the boiler's return from cold temperature as a priority, and if
the
Boiler protection
function is selected, it also protects the boiler from overheating. If the valve is closed (0%
open), the water flows only in a short circuit, while the full opening of the valve (100%) means that the short circuit
is closed and the water flows through the entire central heating system.
CAUTION
If the
Boiler Protection
is off, the CH temperature will not affect the opening of the valve. In
extreme cases, the boiler may overheat, so it is recommended to configure the boiler protection
settings.
For this type of valve, refer to the
Return Protection Screen.
•
Cooling
- set when we want to adjust the temperature of the cooling system (the valve opens when the set
temperature is lower than the temperature of the valve sensor).
Boiler protection and Return protection
do not
work in this type of valve. This type of valve operates despite the active
Summer mode
, while the pump operates
using the shutdown threshold. In addition, this type of valve has a separate heating curve incorporated as a
function of the
Weather sensor
.
➢
Opening in CH calibration
–
When this function is enabled, the valve starts its calibration from the opening phase.
This function is only available when the valve type is set as a
CH Valve
.
➢
Floor heating - summer
–
This function is only visible after selecting the valve type as
Floor Valve
. When this function
is enabled, the floor valve will operate in the
Summer Mode
.
➢
Weather control
–
For the weather function to be active, place the external sensor in a not insolated location, one
that is not exposed to atmospheric influences. After installing and connecting the sensor, switch on the
Weather
control
function in the controller menu.
CAUTION
This setting is not available in the
Cooling
and
Return Protection
Modes.
