Easy to Operate
- A combination of two turnable buttons makes easy access to all functions.
- Even programable functions can be altered at any time by a few key strokes
- Day one set values can be stored and recalled in a simple operation.
- Data concerning how you want the controller to act - the total scenario - can be storedand recalled in one operation.
Unique controlling technique
The controller master that difficult task it is to control both temperature and humidity without the one corrupting the other.
This unique PID-controlling technique has been developed, due to creativity, tests and many years of field operation. The temperature and humidity are nursed with an intelligent mixture of heating, fresh air and - if you want - humidification.
Long range of controlling facilities
- Set values for temperature and humidity can be changed automatically - smoothly through a period.
- The inlet/outlet opening ratio may be depending on outdoor temperature. The cooler the more upwards and time to mix properly.
- The maximum airflow may be limited - littleby little - as outdoor air gets cooler.
- On/off output controlled by ventilation rate and/or humidity (eg controlling heat exchanger unit).
- A timer may be set to switch at a certain rate and duration. Can be made dependent of the outdoor temperature (eg controlling water spraying devices).
- Control-signal for central heating and electric heating. Can control 2 heat-sources in sequence.
- The humidity can also be controlled without the presence of a heat source, by means of lowering the temperature - how much lower is set by user.
Alarms with priority
Soft alarms may be set for high and low humidity and low temperature, making only beeps from the unit. The alarm relay will then be activated only in case of high temperature and sensor/ controller malfunction.
The humidity is measured by means of a wet and dry temperature sensor, which are calibrated once and for all.
All inputs and outputs are protected against transients and electromagnetic interference according to the EMC Directive.
In Case of Power Failure
Time/date and all data stored in memory are backed up by on-board battery.
- Easy setup for back-up during power failure. Works on 12 VDC.
Dr.Pascal stores all measurements, alarms and any altering of values. The last 4-10 days are always retrievable. It has a facility for browsing the data via the display. There is also an easy way to make a search on high and low values. (Eg when did the last alarm event occur?)
Useful possibilities through communication on a network:
- One unit may be set-up to measure outdoor temperature and then broadcast the value to the others.
