10 READINGS
The operating status and the values can be read. Used for
performance checks and for generally checking values,
settings, power consumption, etc.
No values can be altered in this menu group.
Each menu indicates which values can be read.
The operation times per 24 hour period are given under
the OPERATION TIME menu.
11 MANUAL TEST
Note! Manual test running can cause indoor com-
fort problems. There is also risk of overloading the
system. The responsibility for discomfort and over-
load rests totally on the person who activates the
function.
Manual test run can take place for testing the inputs and
outputs, fans and heat exchanger, etc.
Used when the air handling unit is first installed to make
sure that all the connections have been correctly wired.
Most alarms, functions and normal control modes will be
blocked while manual testing is in progress.
On a return to the other menu groups, the controller
resumes normal operation and all settings for manual test-
ing will be terminated.
Each menu indicates which functions can be test run.

9.1.13 anti-frosting protection for the
plate/coil heat exchanger
In cold weather, and if the extract air is humid, there is risk
of frosting in plate/coil heat exchangers. The GOLD PX/CX
is equipped with anti-frosting protection.
GOLD PX (plate heat exchanger)
The temperature inside the heat exchanger’s ”cold
corner” and the humidity in the extract air are measured.
Taking the humidity into consideration, the control system
calculates the lowest permissible temperature without risk
of frosting inside the heat exchanger. The by-pass damper
is then controlled to prevent the temperature from drop-
ping below this limit.
GOLD CX (coil heat exchanger) and
GOLD SD with coil heat exchanger
The temperature of the liquid circulated to the extract air
coil and the humidity in the extract air are measured.
Taking the humidity into consideration, the control system
calculates the lowest permissible temperature without risk
of frosting inside the coil.
The valve in the pipework package is then controlled to
prevent the temperature from dropping below this limit.
