INTRODUCTION
1.1 General
The new
GCD 036 DCR, GC 36-43 DC INVERTER
split unit range comprises the
following RC (heat pump) models:
•
CKD 036
•
CKD 045
Remote control compatibility
The
units are compatible with remote controls RC3, RC4, RCW1, RCW2, RC7.
Inverter description
Unlike standard units (fix RPM) that are selected according to their nominal capacity to
overcome the maximum required load, DC Inverter units can be selected to a smaller
nominal capacity range unit.
It made possible due to the ability of inverters to reach a much higher capacity level
(indicated as Maximum Capacity) which is around 115-130% of the nominal capacity.
