(FIGURE 2-1) FIELD WIRING CONNECTIONS

A. Outdoor Sensor - outdoor air sensor, set point will adjust based on outdoor air temperature (not

needed if 0-10 VDC output is connected)

B. External sensor connection - system temperature sensor, senses water temp in a storage tank or

a heating loop.

C. Indirect Tank Sensor - Sensor for indirect DHW. An aquastat may also be connected here.

D. 0–10 VDC - connect a 0–10 VDC output here to vary set point temperature.

E. Additional Heat Source - dry contacts that will close a thermostat on an extra heater/boiler if the

cascade system is at 100% of capacity.

F. Lock Out Signal - alarm bell or light may be connected here to indicate that the boiler is a hard lockout.

G. Remote Thermostat - normally jumped. A room thermostat may be connected here to enable/

disable the heater/boiler.

H. Cascade Connection - communication cables get connected here and “daisy chained” to all heaters/

boilers in a cascade. This is polarity sensitive.

I. 3-Way Diverter Valve - Used in a boiler system with both Heating and Indirect Hot Water.

J. P2 - Pump for indirect. Used in a boiler system with both Heating and Indirect Hot Water.

K. P1 - Wire to primary pump for boilers.

L. P3 - Wire to primary pump for heaters or system pump for boilers.

M. Power Supply - connect 208–240 VAC single phase power supply here.
