C325TZ - Temperzone
Current firmware - v1.0
Temperzone Compatibility:
Units with UC8 board or above (not all the units with UC8 boards are compatible)
It is NOT compatible with UC7 boards or before.
The new R32 Econex units (for example ISD 351LYX and ISD 251LYX units) and Eco Ultra DO NOT work with the iZone controller at the moment.
Wiring polarity between UC8 / UC9 board and C225 IS Critical.
Can use RA, Zones, Master or RF as controlling sensor.
Connect a shielded, 2 core, twisted pair control cable from the C225 to the UC8 or UC9 board in the condensing unit. This cable is supplied by the installer and not included in iZone kit.
Ensure the dip switches in the condensing unit are set correctly for the installed compressor type (digital / fixed speed) and fan speed control. Refer to the Temperzone unit / service manual.
C225 Module: iZone C225 module must have a C325TZ AC interface connected.
A: Connect A wire on the left side of the CPU (closer to the AC interface).
B: Connect B wire on this side (closer to the Port #7).
