Controlling 2 rooms
Dr.Gemini can control 2 rooms, individually.
Simple, switch between rooms by pressing one button.
Easy to operate
A combination of two selector control knobs makes easy access to all functions.
Advanced operations are easy to perform.
- 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 stored and recalled in one operation.
Unique controlling technique
The climate controller masters 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
- Fan speed, outlet dampers and air inlet flow can be controlled according to individual curves.
- The maximum airflow may be limited - little by little - as outdoor air gets cooler.
- Set values for temperature and humidity can be changed automatically - smoothly through a period.
- The humidity can also be controlled without the presence of a heat source, by means of lowering the temperature.
- A timer may be set to switch at a certain rate and duration, e.g. controlling water spraying devices.
- Alarms are transferred using RS485.
- Alarm for high or low temperature, humidity and broken sensor cables.
- In case of sensor failure the controller keeps running using last valid measurements.
- Local network monitors actuators, fans and cables.
Alarms with priority
Soft alarms may be set for high and low humidity and low temperature.Temperature alarms can be made dependant of outdoor temperature, i.e. how much may indoor temperature excecd outdoor temperature, before an alarm is generated.
The humidity is measured by means of a wet and dry temperature sensor, which is very reliable.All inputs and outputs are protected against transients.
Since actuator motors, fan controllers and relay functions are connected in a 2-wire network, wiring is reduced.
The built-in data logger stores all measurements and controller parameters - stamped with date and time. These data may be shown as trend curves on a PC.
Useful possibilities through communication on a network.
- Service can be made from a telephone.
- One unit may be set-up to measure outdoor temperature and then broadcast the value to the others.
Using a PC, directly or through a modem:
- Transfer the logged data, convert these to graphics using Professor Partyline. Any irregularities will be clearly displayed.
- Great survey over a number of units, with the possibility of making all necessary operations by remote control.
An optional SPEECH-PROCESSOR Dr.Bell expands the possibilities:
- Automatic alarm calls informs in clear speech.
- From a telephone you can perform remote control. All operations are confirmed in clear speech
