4.20.1. FUNC - Defining valve function
Acronym Scrolling message Submenu Attributes
FuNC VALVE CONTROL FUNCTION VALVE R W
The parameter shows and sets the valve function, i.e., if it controls a heating or cooling system.
Unit of measurement: -
Options: HEAT1 = PID.1 heat control power
COOL1 = PID.1 cool control power
if it is enabled PID2.E in EN.FUN function:
HEAT2 = PID.2 heat control power
COOL2 = PID.2 cool control power
4.20.2. KEY.MO - Enabling valve operation with keys
Acronym Scrolling message Submenu Attributes
KEY.MO VALVE OPEN/CLOSE FROM IN/DEC BUTT ENABLE VALVE R W
The parameter shows and sets enabling of valve opening and closing with controller keys
and in manual mode.
Unit of measurement: -
Options: OFF = Keys do not act directly on valve opening and closing
On = Keys enabled for manual valve opening and closing
4.20.3. TRAVL - Valve actuator travel time
Acronym Scrolling message Submenu Attributes
TRAVL ACTUATOR TRAVEL TIME VALVE R W
The parameter shows and sets the time taken by the actuator to bring the valve from “full open” position to “full closed”
position or vice versa.
The time is obtained by trial or deduced from the valves technical data.
Unit of measurement: Seconds
Options: 0...2000
4.20.4. TIM.LO - Minimum power change for valve drive
Acronym Scrolling message Submenu Attributes
TIM.LO MINIMUM PULSE TIME VALVE R W
The parameter shows and sets the minimum power change needed to drive the valve.
The parameter is calculated as a percentage of the TRAVL parameter and serves to prevent excess activity of the valve,
with consequent electromechanical stress.
The control function is explained in detail in paragraph “5.14. Managing motorized valves” on page <?>.
Unit of measurement: % di TRAVL
Options: 0.0...25.0
