Description
REPLACEMENT CONTROLLER FOR ECOFLOW PLATE HEAT EXCHANGERS AND STOKVIS ECONOPLATE PLATE HEAT EXCHANGERS.
DETAILS:
The EcoFlow Controller is a purpose designed PID regulator which controls temperature via a motorized modulating valve as well as operating a number of primary and secondary pumps, as can be fitted to the various EcoFlow units.
In addition to the PID regulation, the controller includes:
- Valve opening/closing and P1/P2 primary pump running functional indicator lamps
- Twin-head pump duty share (if fitted).
- High/low temperature alarm indication.
- Volt free common temperature alarm terminals.
- High temperature lockout.
- A safety extra low voltage (SELV) external interlock circuit for connection of an external safety device or switched circuit.
- A safety extra low voltage (SELV) external time clock circuit for connection of BMS time control.
Time control can be by: either the internal inbuilt 7 day time clock for either 2 temperatures of operation or a single temperature set point and night “off” per day, or externally using the safety extra low voltage (SELV) external clock circuit for either 2 temperatures of operation or a single temperature set point and “off”.
Primary pump fault indication/overload trip is displayed on the Controller for units fitted with Magna3 variable speed pump(s)
Duplex twin-head primary pump duty share facility is included as standard.
Duplex twin-head primary pump auto-changeover on pump fault is included as standard for units fitted with Magna3 D variable speed pumps, and for units fitted with UPSD fixed speed pumps only when fitted with contactor and overload
