If you experience frequent or prolonged power outages we recommend installing backup power. A generator
can provide power to the boiler as well as the pumps, blowers and other devices in your home heating
system. An experienced plumbing and heating contractor will be able to assist in implementing backup
power solutions. Please consult a licensed electrician for the correct installation and wiring of your backup
generator. Backup power options include:
Universal Power Supply
UPS units provide 115V power to operate the Frontier Series and parts of your
home heating system when power is lost. While running on battery, an alarm beeps.
The UPS can be configured with varying lengths of run time. UPS battery life
differs based cost, usage and environment. It is typically recommended that the
batteries be changed once every three years.
Pros: Will continue to operate the furnace 1 or 2 core home heating pumps for
power outages of short duration; simple, with no moving parts.
Cons: Will not power forced-air fan systems or more than a few pumps. Cost will
be proportional to duration of outage coverage.
Installation difficulty: Moderate. Additional electrical and plumbing work may be
required.

Auto-start Generator
Complete home emergency power back-up systems are packaged with auto-
start generators and automatic power transfer switches. These systems will
automatically start and provide power to the critical home electrical circuits
when your power is lost. They will continue to operate until the power returns.
Pros: Will heat and power the entire home until power resumes.
Cons: Expensive.
Installation difficulty: Will require a professional electrician.

Auxiliary Wiring for On-Demand Zones
The Frontier CX On-Demand Zone capability
optimizes efficient combustion and provides
thermal spike protection by enabling the
Greenwood Boiler Control to manage part of the
heat demand. This ‘smart buffer’ can be any single
or combination of zones including heat handlers,
radiators, storage tanks, domestic hot water, or
pools. Relays on the Frontier CX control board
control the opening and closing of the selected
zones based on the system’s Clean Burn algorithm.
Note: On-Demand Zone functionality is not active
in some Frontier CX boilers.
