Introduction
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.
