The optional group controller shows on the LCD screen the capacity and power consumption of the product
of instantaneous capacity multiplied by instantaneous input both estimated from the current, etc. within the
group controller.
Cumulative operation hours and start-up count display
The module controller shows the cumulative hours of operation and the number of compressor start-ups on
the LCD screen on a module-by-module and compressor-by-compressor basis.
Operating spray signalling
The module controller provides a signal that indicates the status of the spray for external status monitoring
(close when at least one spray is operating and open when all the sprays are off).
Other output signalling (module controller customization)
(1) Group output for peripheral devices:
Use it to group together a heat pump and peripheral
devices such as air conditioners.
(2) Group output for defrosting:
Use it to provide a signal that indicates defrosting is being
performed (Closed contact to show defrost operation and
open contact for normal operation).
(3) Output for freeze protection pump operation: Use it to provide a signal that indicates the pump is
performing freeze protection operation (Closed contact to
show freeze protection operation and open contact for
normal operation).
(4) Output at maximum-capacity operation:
Use it to provide a signal that indicates that the heat pump
is operating at its maximum capacity (Closed contact to
show maximum capacity operation and open contact for
normal operation).
(5) External heater output:
Heater ON/OFF can be output by the outside air
temperature.
