产品简介

GDRT-1100 GDRT-ONF比例数字温度控制器

详细介绍

 

PROPORTIONAL DIGITAL TEMPERATURE CONTROLLER(GDRT-1100)
The GDRT-1100 is a microprocessor based wall mounted roportional integral(PI) temperature controller for controlling fan coil unit heating and cooling applications.
It has a large and clear LCD display which is both aesthetic in design and user friendly in operation.
  - Microprocessor based
- Ultra slim design
- Large user friendly LCD 3 digit display with back light
- Optional remote sensor terminals
- Very simple installation
- Integrated termination module with room display in one unit
- Universal mounting

The controller provides an analogue 0 ..10 VDC output for controlling motorized or thermal actuator.
Simultaneously there are two triac outputs for controlling 3 point floating actuator.
A startup delay will reset the actuator to close position.

▶Sensor:
- Temperature sensor : NTC 10KΩ
- A trimpot is provided under the front bezel for final caliberation of the sensor
▶Display :
- Press ON/OFF button on the right
- The LCD display the actual room temperature, the unit in ˚C, valve position %
and heat/cool icon.
▶Operation :
- The left button is provided for changing the operation modes of the temperature controller
- The set point can be changed by pressing the add(TOP) or subtract(BOTTOM) button
- Leaving the buttons untouch for 5 seconds will revert the LCD to temperature
display mode
- Switch off by the ON/OFF button, the valve automatically closes.

In case of installing on Panel, make the hole for 9 mm (diameter) first.
Unscrew the nut of potentiometer axis, fix axis to the hole from inside to outside of Panel.
Attach Setting Knob to axis on 0 (zero) point setting. Power source is AC 24V.
In case of using several actuators combination, it's preferable to decide capacity of transformer after collecting each Actuator's power consumption
