COPELAND EAZYCOOL™ ZX CONDENSING UNITS

XCM25D CONTROLLER PARAMETER LIST

Copeland EazyCool™ ZX Condensing Units are equipped with an XCM25D electronic controller from Dixell. The controller design allows the installer to start
and operate the system with minimum effort in terms of controller adjustments. The most important controller settings are described in the application
guidelines and most likely there is no need to change those settings.

In case of special applications additional parameters might have to be adjusted according to those special needs. This document contains the full list of
available parameters in the XCM25D controller. It is not a user’s manual. For questions about how to handle the controller and for functionality description
please refer to the dedicated documentation available at www.climate.emerson.com/en-gb.

Legend
L1 = Parameter in level 1 (without password)
L2 = Parameter in level 2 (with password = 3 2 1)
N.V. = Parameter not accessible

NOTE: When changing parameters C01 (Cin), C02 (CoU) and C05 (CPb) a reset of the controller (interruption of power supply) is required.
