APC4
Description
The APC 4 is a low cost, simple to operate fan speed or variable heater triac controller. It uses a remote sensor to monitor house temperature and two adjustment knobs on the front panel to set the required temperature and minimum fan speed. An override switch is provided to enable the fan/heater to manually operate at full power. A movable link is located on the circuit board to select either cooling or heating modes. The set temperature range is from 15 to 40 °C and the maximum load current is 4 Amps (enough to control a 630mm fan).
