8. WIRING ALL SMART CONTROL ™ MODELS
The Smart Control™ incorporates all the switching and temperature control functions necessary to control the BoilerMate™.
The diagram below shows internal wiring and the associated functions.
After wiring is complete, insert the white thermistor (sensor) plug into the receptacle at the base of the Smart Control™. Select
the plug marked CIRCULATOR or ZONE VALVE based on the application. Zone valves can be slow actuating. Therefore, the
zone valve sensor contains a built-in temperature offset to account for the time it takes the zone valve to fully close. This results
in potable water temperature that is representative of the Smart Control™ temperature set point. This is why it is important
to install the correct sensor into the Smart Control™. See Page 2 for information regarding the selection of a circulator or
zone valve.
