Controls, power units

The control centre for the CPP 60 ventilation system is an RLS 45 K room air control (= master, 230 VAC).

The system can be expanded on the RS 485 bus with a maximum of 3 additional RLS 45 K slave controls and up to 3 PP 45 LT power units. The additional RLS 45 K must be defined as slaves in service mode or with the commissioning software → Operating instructions or installation instructions.

The ventilation units (1 to 8 CPP 60, 12 VDC) are also connected to the RS 485 bus. The connection is made in the RLS 45 K control at the RS 485 terminals.

Installation recommendations: Install CPP 60 controls and PP 45 LT power units in a deep flush-mounted box. If connecting more than 2 components, install them in a double flush-mounted box or in an additional flush-mounted box.
