Reading temperature (0.0°C till 51,0°C). This is the actual temperature. If the control by temperature is
selected, this temperature is used to determine wetter the misting should be switched on or off.
Note I: if you have selected the Fahrenheit reading, this temperature will be shown in Fahrenheit.
Actual time (00.00 till 23.59 hour)
Note I: if the power is off the clock will stop running. All settings remain in the memory.(Backup)
Installation instructions
The controller disposes of an installer's program that makes it possible to adjust the controller to the user's wishes.
In addition, the program can be used to calibrate the controller. Starting up the installer's program goes as follows:
Disconnect the controller from the mains power supply.
Press the SET key and hold it pressed.
Connect the controller to the mains power supply again.
As soon as the display lights on, the SET key can be released.
The installer's program has now been started up, which is made visible by a flashing point behind the third digit in
the display.
With the selection knob a selection can be made from the various installer's functions. The following functions will
be possible:
Calibration temperature sensor (already done at works)
The display now produces the measured current temperature of the room sensor. By turning the +/-
control knob this measured current temperature can be adjusted to one's personal wish. Adjustment of
this measured value is done as follows: Select this function. Measure the temperature near the room
sensor with an accurate thermometer. Turn the +/- knob, until the display indicates the same value. Next
press the SET key to store the calibration into memory.
Note: Carry out the calibration only when the temperature at the room sensor is 10°C /50 F or higher.
P-band cycle time (1,0°C till 10,0°C).
This is the number of degrees where in the cycle time will be regulated from maximum cycle time till
minimum cycle time. Remark: this setting is always in Celsius, even if you have selected Fahrenheit.
Example:
Mode valve = 3 (on temperature base)
On-time valve = 30 sec.
Maximum cycle time = 10 minutes.
Minimum cycle time = 2 minute.
Set temperature = 20,0°C
P-band = 10,0°C
When the actual temperature is below the set-temperature (< 20°C) the valve is always switched off. As
soon as the actual temperature reaches the set-temperature (= 20°C) the valve is pulsed on and off. The
on-tie is 30 seconds and the total cycle time is 10 minutes. (= maximum cycle time). So the valve is
switched on for 30 seconds every 10 minutes. When the temperature is rising the cycle time decreases
and the valve will be switched on more often. The maximum pulse frequency will be reached as soon as
the actual temperature reaches 30°C (set-temperature + P-band). The valve then is switched on for 30
seconds every 2 minutes. See table below.
