Alarm view

Select this menu by pressing the key when you are in the main overview screen. Then select

the ‘Alarm view’ menu item and press the key. When there is no alarm, the screen shows ‘No alarms’. When there are alarms, the screen shows what kind of alarm it is. You can select an alarm by

pressing the or key. Then press the key and a screen is shown which asks you whether you want to suppress this alarm or not. When the alarm is suppressed the alarm relay(s) will be activated again. (= no alarm) If this alarm is still present after a few minutes the alarm is released again.

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

key. Each day it is recommend that this

Page 8

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.
