NOTES:
1. For ZONE 1-3 to output 24VAC (like in this example), jumper ZONE INPUT to R (24V).
2. NTI Room Sensors can be used in place of convential room thermostats. Daisy-chain B & T of each sensor to BUS terminals B &
T at the boiler, taking care to match polarity. Each room sensor must be configured for the zone it is located in.
3. Only the BOILER PUMP can be a variable-speed type and controlled by the boiler; figure illustrates 0-10V control.
