4. CONFIGURATION
4.18.1. F.uAL - Defining valve function
Acronym Scrolling message Submenu Attributes
F.uAL VALVE CONTROL TYPE 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: HEAT = Heat control power
COOL = Cool control power
4.18.2. 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
4.18.3. 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
4.18.4. 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 153.
Unit of measurement: % of TRAVL
Options: 0.0...25.0
4.18.5. TIM.HI - Impulse mode setpoint
Acronym Scrolling message Submenu Attributes
TIM.HI IMPULSIVE MODE INTERVENTION THRESHOLD VALVE R W
The parameter shows and sets the impulse mode setpoint as a percentage of valve opening time TRAVL.
The control function is explained in detail in paragraph “5.14. Managing motorized valves” on page 153.
Unit of measurement: % of TRAVL
Options: 0.0...100.0
