(14) Evaporating temperature correction at night-time, using an external contact
The 2 methods can be used to increase the evaporating temperature at night-time:
1. Receiving the time setting from the AIRNET (Setting Mode 2-11).
2. Using an external contact.
The following describes the wiring needed to use an external contact.
By a short circuit between terminals A and C on the PCB (A6P) in the control box, the evaporating temperature can
be corrected at night-time.
For details about the wiring, refer to Figure 1. Protect the terminals using insulation sleeves or equivalent.
When used in conjunction with a remote switch, connect the wire to the terminal using a ring connector (refer to
Figure 2), or connect it to terminal C (refer to Figure 3). The terminal connectors must be protected with insulation
sleeves.
By using the Setting Mode 2-11, you can change the amount of evaporating temperature shift that is allowed during the
night-time evaporating temperature correction.
The shift amount is factory setting to 1°C.
Moreover, the signal from the external contact will take precedence over the setting specified in Setting Mode 2-11.
Note:
Since this wiring is weak electrical, ensure the wiring route is at least 50 mm or more away from
strong wiring.
