Water discharge
activation/deactivation of the solenoid valve to discharge the tank.
This key works in a similar way to a switch, the solenoid valve is activated when it is pressed. When it is pressed
again, the solenoid valve is deactivated (“
toggle
” switch).
To activate it, the key must be held down for 3 seconds, whereas deactivation is immediate.
If the level sensor is fitted, the water stops loading as soon as the maximum level
is detected by the sensor.
If the solenoid valve is active, the discharge icon flashes
If the solenoid valve is deactivated, the discharge icon stays on
Refresh
This reloads the last time value set on the selected timer.
Operation
–
All the functions listed above can be selected using the function keys or the push encoder, as described in the general
introduction.
–
During setting, the value to change will flash.
The hours/minutes or minutes/seconds on the timer are modified separately.
–
If confirmation is not given within 5 seconds, it will automatically validate the displayed value.
–
The unit begins heating when the value of the regulation probe is lower than the set value; heating will be interrupted
when the value is higher. Heating is restored in the same way, when the value goes down again.
Regulation continues until the regulator is not switched OFF.
–
When the set temperature is reached, a warning icon
will appear on the screen.
The icon will disappear only when the temperature setpoint is changed or the controller switched
off.
–
Water filling:
if the controller goes from OFF to ON and the water level sensor is fitted, the water load valve will be managed
as follows:
initial activation is always carried out using the key (keeping it held down) and the valve will automatically be deactivated once
the maximum level has been reached.
Once the maximum level has been reached, if the water level goes below the minimum level set by the sensor,
the load valve will automatically be activated/deactivated.
After the first load, the load key will force the valve to be activated, if kept held down (the valve closes when released).
To load the water once again, at least one water discharge has to be carried out or the device switched off and then back on
again.
If the water level sensor is not fitted, water must be loaded manually.
–
The device will interrupt heating:
–
when it is switched OFF
–
during every water load and discharge (either activated by the key or if the sensor is fitted)
–
When countdown ends (time at 00:00), the buzzer will sound until the button on the push encoder (or one of the 6
function keys) is pressed or until the timeout interval set by the relative parameter (e2) elapses, with a cycle of 0.5
“ON/0.5” OFF. This does not affect the regulation, the device will continue normal regulation.
Management of technical room fan output and ON-OFF output
–
If one of the available outputs is configured as “technical room fans” (value set to 11), the fans are always on
(except for models with J/K thermocouples, where they are activated when the threshold set by parameter r37
is exceeded).
–
–
If one of the available outputs is configured as “ON-OFF” (value set to 14), the relay will operate as follows:
–
OFF when the device is on stand-by mode
–
ON under all other conditions
