Electrical Controllers
Auto change over panel for the ITEC twin fan range using current sensing. Duty sharing (8 options from 4 to 24 hours),Manual selection, variable overloads, Alarm output for BMS. Built in trickle and boost with adjustable speeds. Rated maximum power is 8 Amps, IP 40. Dimensions 190W X 240H x 70D.
Passive infra red sensor for switching fans of up to 6 amps on with a built in run on timer. Can be ceiling or wall mounted and either flush or surface mounted.
Robust electronic thermostat offering on /off control of electric devices such as fans and heaters. Maximum current 16 amps with a temperature range of 0 to 50 degrees centigrade. The casing is impact resistant light grey polymer offering an IP 54 enclosure.
Room humidistat to monitor the air humidity in the room and switch on a fan or fans to change the air and reduce the humidity.
Reversing switch for reversing the rotation and air direction of axial flow fans. Suitable for axail fans upto 5.5 kW and both single and three phase.
Overheat protection for fan motors with TK connections (that is most of the Helios range). The MW is a single phase overheat protection unit and the MD is a three phase overheat protection unit The TK or thermal cut outs monitor the temperature in the motor windings
A duct mounted paddle switch that sensors the airflow velocity and indicates when there is too much or too little airflow. With an adjustable set point and requires a minimum duct size of 315mm.
Duct sensor with temperature probe to monitor duct air temperature and control the CV heater range.
Room temperature sensor to monitor room duct air temperature and control the CV heater range.
The controllers are suitable for constant supply air control and constant room control. In case of rapid temperature changes in the supply air, a PI control behaviour is achieved; in case of slow changes in room air, the control behaviour corresponds to a P-controller. Automatic night-time reduction can be achieved using an external, on- site timer.
For ventilation systems in conference rooms, restaurants, shops, production facilities, residential / community rooms.
