INSTALLATION
The RPT-20T is intended to be mounted in a wall socket. The
thermostat should be mounted on the wall approx. 1.5 m above
the floor in such a way as to allow free air circulation around
it. Draughts and direct sunlight or other heat sources must be
avoided.
The baseplate is equipped with multiple screw holes. Please use
the drill template for guidance; see fig. 7. The baseplate should be
fastened by minimum two screws tightened to a max. torque of
0.8 Nm.

You can connect the RPT-20T Room panel to a GreenZone Module
using a Modbus cable. The Modbus cable can connect to the RPT-
20T Room panel by a RJ12 6P4C connector or four single wires.
There is no difference on features or behaviours using either RJ12
6P4C or screw terminals.
Modbus RJ12 6P4C
The Modbus cable is connected to a GreenZone Module Modbus
sensor port and the RJ12 6P4C port on the RPT-20T; see fig. 3.
Modbus Screw terminals
The Modbus cable can be connected to a GreenZone Module
Modbus sensor port and the corresponding screwterminals on the
