Hydromatic II Control Board - ASY-250-X0G
The Hydromatic II system is a water temperature controller for use in loop
circulation systems. It provides outputs for reverse cycle and electric heater operation at
each control.
Features
- Modular system for controlling one to eight compressors.
- Directly drives AC contactors from 24 to 250 VAC.
- Integrated touch screen OLED display.
- Universal 115/230 VAC 50/60 Hz power supply
- Simple CANBUS (Computer area network) two wire connection between
controls. - Remote mounted tempered water and sea pump control board with pressure sense
and flow inputs. - Optional stage current sensing and over current shutdown.
- Optional high and low Freon pressure transducer inputs.
- VFD (Variable frequency drive) dry contact output.
- MODBUS input for VFD monitoring.
- Electric heat only transitioning based on sea water temperature.
- Auxiliary voltage input allows using contactors with operating voltages different
from the supply voltage. - Automatically equalizes compressor run times in multistage systems.
- Programmable temperature controlled staging for efficient operation.
- Automatic slave bypass and retry for a slave with a fault.
- Cycled or continuous sea pump operation.
- Compatible with AirNet 5 (internet / network access).
- Sea water temperature sensor.
- Individual tempered water flow switch inputs for each compressor.
