Cable routing The following image shows recommended cable routing from the distribution box to the condensation water trough on the inside of METROAIR I. Transition between the electrical cable and the heating cable must occur after the lead-in to the condensation water trough. The distance between the distribution box and the lead-in to the condensation water trough is approx.
Software version Optional connections In order for METROAIR I to be able to communicate with indoor module / control module the software version Communication must be according to the table. METROAIR I communicates with METROTHERM indoor Indoor module / Software version modules/control modules by connecting a three core, screened cable (max area 0.75 mm²) to terminal block Control module...

6 Commissioning and adjusting Preparations Start-up and inspection Check that the pipe system is prepared. 1. Communication cable, terminal block (X22:1-4) must ■ be connected. Check the pipe system for leaks. ■ 2. If cooling operation with METROAIR I is wanted, DIP Check that the electrical installation is prepared.
Adjustment, charge flow For correct function of the heat pump over the entire year, the charge flow must be correctly adjusted. If an METROTHERM indoor module METROAIR 330 or accessory controlled charge pump is used for the control module METROAIR S20 / METROAIR S40, the control tries to maintain an optimal flow across the heat pump.
