The HCP7-F has been purpose built to comply with AS1668.2 Car Park CO control requirements in occupied & non occupied non naturally ventilated car parks. The controller can also be set to respond to NO2 sensors. Output operation can be easily set as 2 speed on/off or to modulate a fan via a VSD. Forced fan ON overrides are available & interlocked with internal time switches both for peak times and to start after an adjustable idle period for minimum ventilation requirements. The HCP7-F can read up to 7 Hevac HGS sensors directly or via expansion modules (EXP7) up to 42 sensors. External monitoring is also available via RS485 MODBUS. All
output relays are voltage free permitting the use of AC or DC circuitry and are rated at 240v 8A. The HCP7 can be powered from 12-24 v DC or AC.
