ELECT 5.2

Indoor/Outdoor controller c/w Optional Standard Thermostats

Application:

StatLink

controls activating individual manifold module zone motors and automatic mixing

valve reset controller which in turn activates boiler plus primary (P-2) and system (P-1) pumps.

DHW tank aquastat opens DHW valve and activates boiler plus primary (P-2) and system (P-3)
pumps.

Note:

• Drawings are for HeatLink

suggested

electrical schematics only! User must determine if electrical schematic will work for their particular application.

User must also confirm all HeatLink

schematics with manufacturer schematics of each particular control chosen.

• In all cases manufacturer equipment schematics will take precedence over HeatLink

electrical schematics.

• All wiring as per applicable electrical codes!
