Mechanical Design and Installation
The unit consists of two parts: (a) The mounting plate and (b) the cover with the transmitter.
Mounting Location
Mount the transmitter on a flat interior wall of the room to be controlled. Do avoid obstructions such as shelves, curtains and
recesses. Do not place near heat sources, draft channels. Do not expose to direct sunlight.
Mounting instruction
See installation sheet no. 70-000572 (www.vectorcontrols.com).
Configuration
Output signal configuration
The analog output signal type may be configured with a jumper for 0-10 VDC or 0-
20 mA control signals. The jumpers are located next to the terminal connector of
each analog output. See table below for jumper placement. The factory setting is
to 0-10 VDC.
The signal range may be set with JP2 for both analog outputs. JP2 will only operate
if the output range specified with OP01 and OP02 is left at the default position of
0…100%. With any other setting the position of JP2 has no influence and the range
defined with the output parameters applies.
