Connect Switches and Sensors
The unit can be switched to boost by a variety of methods:
Applying 240 V to the LS input .
Switching across 1 of 5 pairs of switch terminals.
Applying between 0 and 10 V as a proportional input to two input terminals.
N.B Alternative functions are assigned to SW/1, SW/2, SW/3 & SW5 when Control Mode 02 is selected in
the start-up screens see Appendix One for further details.
In addition, fitting a Vent-Wise Accessory to the unit means that switch terminals 1-3 can be connected to be
switched by a current detector (for example, detecting a hob being switched on) or a temperature sensor (for
example, detecting the flow of hot water). Terminal 4 can be used in conjunction with a momentary switch or
switches.
Connect any switches or sensors required to control the unit by connecting to the terminal connectors at the
bottom of the control unit as shown below and in Table 1. If necessary contact Vent-Axia regarding the wiring
and fixing of accessories and sensors.
The cable entry back plate may have grommets or easy knock-out positions. If the knock-outs are used then
ensure that you use a grommet or gland to protect against potential water ingress.
When fitting external controls the appropriate cord anchorage and glands, according to country
requirements for cable size should be fitted, these glands should have a minimum water ingress
protection of IPX2.
Other means of connecting the
unit can be used if they meet
the local wiring regulations.
