Installation Of Thermistor For Suction And Discharge Air Stream; Matching Outdoor Unit Capacity With Ahu Kit Capacity - Panasonic PAW-160MAH2L Installation Instructions Manual

4.4.4 Installation of thermistor for suction and discharge air stream

Mount the suction and discharge air thermistors according to the following instructions.
1. For ECOi, ECO G and PACi systems, attach the suction air thermistor (TA) to the position
where air suction temperature can be measured.
2. In addition to this, for ECOi and ECO G systems attach also the discharge thermistor (BL) to
the position where air discharge temperature can be measured.
3. In case of using the additional thermostat (advanced version only) for:
a. target temperature setting based on ambient temperature, install the 3-wired temperature
sensor in a protected location suitable for detecting the proper ambient temperature (avo-
id direct sunlight and moisture);
b. demand control based on room supply air temperature install the 3-wired tempera-
ture sensor in the blow-out duct of the AHU where the proper air temperature can be
measured.

Matching outdoor unit capacity with AHU Kit capacity

Matching outdoor unit capacity with AHU Kit capacity – PACi systems
As there is only one fi xed-capacity AHU Kit model (PAW-280PAH2(L/M)) available for combina-
tion with the complete range of PACi systems, where the outdoor unit capacity is also fi xed for
each model type, it is necessary to change the settings so that the default capacity check of
the PACi outdoor unit is ignored and the outdoor unit capacity can be matched with the AHU Kit
capacity.
There are three diff erent methods to achieve this aim.
Method A: Cutting JP001
One possibility is to cut jumper JP001 on the outdoor unit main PCB.
1. On the PACi outdoor unit PCB, cut the wire of jumper JP001 at two positions, and take the
cut jumper leads off . Depending on the PACi outdoor unit model, it can be found on the main
PCB at one of the following positions:
