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 for detecting the proper ambient temperature (avoid 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.
4.5 Disconnection of jumper on outdoor unit PCB
Disconnection of jumper on outdoor unit PCB – PACi systems
In order to avoid the controller displaying the error message L10 or L13, jumper JP001 on the
PACi outdoor unit PCB must be cut.
1. Cut wire of jumper JP001 at two positions.
