Microprocessor Controller for Aquatherm RA Series Temperature Controllers

The temperature accuracy of every unit depends on its control system — Aquatherm RA Series temperature controllers come standard with a microprocessor based control system designed exclusively for Thermal Care. The panel's two large digital displays make it easy to set and read system temperatures. The entire control panel is simple to understand and operate without confusing codes or useless buttons.

Options include:

Hand held remote control panel
Alarm horn
"From Process" temperature readout
Return water temperature display
Remote alarm contacts
Remote on/off contacts
SPI communications

Screens include:

Dual LED digital displays of "To Process" and "Set Point" temperatures.
15 diagnostic LEDs and 7 snap action switches.
Entire panel surface is sealed protecting against contamination from dirt or water.
High temperature safety set for 260°F.
30 minute deviation delay stops nuisance alarms during start-up and set point change.
Viewing angle makes panel easy to read.
Easy reset of control panel alarms from front panel.
PID control for ±1°F accuracy.
Easily switch between °F and °C temperature readout from front panel.
Automatic fine tuning of PID parameters.
One minute air purge cycle with safety cancellation above 150°F.
Self-adjusting high and low temperature deviation alarm set points.
Low voltage fail safe sensor interlocked with control circuit.
Built-in sediment trap settles contaminants away from the pump seals.
Seal saver automatically cools process water to 90°F to lower hose temperatures and to prevent potential burns to the equipment operator.
