Model Range
 | Trackmaster Twin Fan Controller (ITC) The ITC model provides automatic changeover on fan failure as well as enabling a manual selection of either fan for duty sharing or test purposes. (BMS compatible via volt free contacts). This controller must have a permanent live supply. Any On/Off switching must be via the sensor connections S1 and SG terminals.
| ||||
 | Trackmaster Twin Fan Controller (ITC-DS) The ITC-DS model (Duty sharing). Incorporates a timing mechanism which operates alternate fans on 12 or 24 hour intervals, thus ensuring the extended life of the fan bearings. The controller also provides automatic changeover on fan failure along with the facility for manual selection of either fan. (BMS compatible via volt free contacts). This controller must have a permanent live supply. Any On/Off switching must be via the sensor connections S1 and SG terminals
| ||||
 | Remote Visual Indicator (RVC) Wired in conjunction with either an ITC or ITC-DS controller the RVC can be located up to 100m away using low cost ELV wiring.
