Controller Setup - Electro Industries EB-MA-10 User Manual

11. Close "water supply valve" and disconnect water supply.
12. Optional – energize circulating pump during this fill operation. The water pressure from the
household system and as plumbed should typically flow through the circulating pump without the
pump running.
COMMENT: Purge one loop at a time.
The front panel contains a red temperature select "knob" with two selection ranges – high mass/low mass.
Certain internal sequence timings and operating stage differentials adjust themselves according to the
switch position. The high mass positions have a longer sampling delay and greater temperature
differential to prevent rapid stage cycling.
The front panel allows selection of operating temperature. The table below should coincide with the
decal on the front panel.
Circulator pump mode – as factory set, the circulator pump is controlled directly from the "W" input
terminal. In this setup the circulator pump continues during load control interrupt (or optional remote
standby switch). There is a provision within the controller board (inside) to allow the circulator pump to
not operate during load control interrupt.
On the inside control board, just above the two
bottom terminal blocks, is a small pin jumper
arrangement. The black "device" sets up the pump
mode. Just below this pin jumper arrangement are
W and L lettering. When the two pin shorting
device is in the W position, the pump is a direct
function of R to W input. When the two pin jumper
is in the L position, the pump is interrupted during a
load control.
WARNING: This shorting device must be in one of the two positions for the circulator pump to properly
operate.
