Additional room air controls (parallel operation)
The connection of additional room air controls takes place on the RS 485 interface on the RLS 45 O / RLS 45 K control → Installation instructions for final installation kit or Commissioning software.
Up to 3 additional, wired controls can be added to a PP 45 / PPB 30 system.
The set operating mode, ventilation level and the additional External OFF function (if set up) apply to all ventilation units.
The other additional functions (sleep mode, intermittent ventilation, supply air mode) are only relevant to units connected to the room air control.
If a room air control is being used as a slave, addressing as slave 1, 2 or 3 (depending on number of slaves) must be selected in the control’s service menu.
