Remark: you can also select the alarm view screen by pressing the period key when you are in the
main overview screen.
Possible alarms:
T-sensor defect This means the temperature sensor is faulty. (or the wiring of the sensor)
Programming! This programming alarm is working as follows: when a valve should be
activated either by temperature, time or manual, the valve is put into a
queue. The control is processing the valve according this queue one by one,
because only one valve can by switched on at the same time. When you have
programmed many valves (with a short cycle time and/or a long active time)
the controller cannot handle the queue. (queue overflow) Now a
programming alarm/warning is given. You should program longer cycle times
or shorter active times to prevent this alarm.
General menu
Select this menu by pressing the key when you are in the main overview screen. Then select
item ‘General’ and press the key. The next readings/settings are shown:
Valve activated. (0 till 10)
This reading shows the valve that is activated at this moment. 0 means no valve is activated.
Temperature. (-70,0C till +130C)
This is the actual temperature measured by the temperature sensor. Remark: When no temperature
control is activated in the installers program this reading is not visible. When in Temp Mode the Low
and High temperature readings are recorded daily in the MIN.MAX Registry. You can select the
Temperature min/max registry by pressing the or key. Each day it is recommend that this

Mist-Time manual Page 7
Min/Max be reset to the actual temperature for the next day. Please see function RESET TIME to
make these changes.
Pband. (1,0 till 10,0C)
This is the number of degrees between the maximum cycle time and the minimum cycle time of the
temperature control. Remark: this function is only visible when you have a temperature control
activated in the MistTime.
Example:
Mode valve = Temp (on temperature base)
On-time valve = 30 sec.
Maximum cycle time = 10 minutes.
Minimum cycle time = 2 minutes.
Set temperature = 20,0°C (68,0°F)
P-band = 10,0°C (18,0°F
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-time 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.

start and stop times. Each set of start and stop times has its own cycle time. The
maximum cycle time is used for this.
Temp The valve is activated as soon as the actual temperature is rising above the set
temperature. The cycle time is calculated between the maximum and minimum cycle time
depending on the p-band. The maximum and minimum cycle time of start 1 is used for
this. Remark: this function is only visible when you have a temperature control activated
in the MistTime.
Ti+Te The valve is activated on temperature base as described in the mode ‘Temp’ but only when
the actual time is between a start an d stop time. There are 6 start-stop times possible.
Remark: the installer can select how many start-stop times are used.
Remark: this function is only visible when you have a temperature control activated in the
MistTime.
Manual The valve is activated immediately for one cycle. After this one cycle the valve mode is put
back to the previous mode. Remark: When there are other valves in the queue, these
valves will be processed first.
Set temp. (0,0 till 50,0C)
When the valve is in de ‘Temp’ or ‘Ti+Te’ mode and the actual temperature is rising above this set
temperature, the valve is activated. The cycle time is calculated between the maximum and minimum
cycle time and depending of the p-band. When the valve is in the ‘Temp’ mode, the maximum and
