Control using CHR room thermostat

Control with 0-10 V BMS signal

Control

InLine comfort panels can either be controlled by a CHR room
thermostat or via an external 0-10 V BMS signal.

When using a CHR room thermostat, the panel and thermostat
are connected with a 4-lead cable. If more panels are added to
the same thermostat, they are connected with a 2-lead cable.

When a 0-10 V CTS signal is used to control the panels, “0” is
connected directly into the panel.

PLEASE NOTE!

“0” will be shared jointly when using several

power supplies.
