The iSolar™ BX is a multi-functional temperature differential controller
with add-on system functions for use in a wide variety of solar thermal
heating applications. iSolar™ BX is equipped with four relay outputs; three
triac pump speed control relays and one standard relay. The controller is
equipped with fi ve Pt1000 sensor inputs, two analog Grundfos sensor
inputs, and one impulse fl ow meter input. Twenty six system confi guration
options are predefi ned for control of a standard solar water heating system,
drainback systems, supplemental space heating, multiple storage tanks,
heat dump and storage tank booster heating. Unique features include built-
in SD memory card slot, built-in clock and calendar, integrated energy heat
measurement inputs, parallel relay operation and drain back control.
Function
SSRs (Solid State Relays) is an isolation
speed control relay which will speed control
up to a 5 Amp solar pump based on the
output speed control voltage of the iSolar
solar controllers.
