Main Controller
The main controller is supplied loose with each cylinder package; it acts as both the commissioning tool and
end user interface (time clock and thermostat). If the main controller is to be utilised as a thermostat then it is
essential that it is correctly located, this may require the cable to be extended, and it must not be left in the cylinder
cupboard. Only when the main controller is not to be utilised as a thermostat may it be installed in the cylinder
cupboard. When placing as a thermostat choose a suitable location that is not likely to be influenced by heat
sources or cold spots (i.e. near radiator/window)
Connect the main controller cable to 13 and 14 on the terminal block (TBI. 2) on the FTC4 (Master) controller.
When wiring to TBI.2, use ring or fork type terminals .The 10m controller cable is supplied loose. This can be
extended to a maximum of 500 m using the same specification of cable.
The main controller can be installed either in the switch box or directly on the wall. Regardless of whether installing
the main controller either directly on the wall or in the switch box the following clearances should be achieved.
