F.ual - Defining Valve Function - gefran 650 Installation And Instruction Manual

4. CONFIGURATION

4.18.1. F.uAL - Defining valve function

Acronym
F.uAL VALVE CONTROL TYPE
The parameter shows and sets the valve function, i.e., if it controls a heating or cooling system.
Unit of measurement:
Options: HEAT
COOL
4.18.2. KEY.MO - Enabling valve operation with keys
Acronym
KEY.MO VALVE OPEN/CLOSE FROM IN/DEC BUTT ENABLE
The parameter shows and sets enabling of valve opening and closing with controller keys
Unit of measurement:
Options: OFF
On
4.18.3. TRAVL - Valve actuator travel time
Acronym
TRAVL ACTUATOR TRAVEL TIME
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:
Options: 0...2000
4.18.4. TIM.LO - Minimum power change for valve drive
Acronym
TIM.LO MINIMUM PULSE TIME
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:
Options: 0.0...25.0
4.18.5. TIM.HI - Impulse mode setpoint
Acronym
TIM.HI IMPULSIVE MODE INTERVENTION THRESHOLD
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:
Options: 0.0...100.0
