Unico and Heating October Pints with Pete
Unico and Heating Unico is involved in all aspects of HVAC, not just Air- Conditioning Unico is known for its outstanding comfort for air-conditioning but also provides superior heating
Unico and Heating
Why Unico for Heating No drafts No streaking of dirt Even Temperatures Duct Efficiency Comfort
The Total Comfort System
Heating Can be used as the exclusive heating source OR Used as supplemental heat for mild weather
Heating We have Five Methods for providing heat Heat Pump Geothermal Hot Water Coil Electric Furnace NEW: The iseries by Unico a great new inverter heat pump for even the coldest climates
Heat Pump Coil
Heat Pump Coil Deeper than Cooling only coil Check Valve on Expansion Valve 24V relay for anti-frost bypass in heating mode

INTRODUCING
Features: Intelligent Defrost: Heats even in the Defrost Cycle!
Outdoor Units
Wide Selection of Indoor-Outdoor Units Remember, Inside Unit Load Cannot exceed outdoor Unit Capacity
Indoor Units
Cold Climate Operation (-25.6 F) -15 C (5 F) +43 C (109.4 F) (122 F) iseries systems fit every installation, both warm and cold climate

HEATING MODULE 2 PARTS Hot Water Coil Coil Box
Auxiliary Heating Can be controlled by: The ISeries control outputs (S1,S2,S3) OR: The Thermostat control for Auxiliary or Second Stage Heat
Auxiliary Connect the heating source (hot water coil or electric furnace) to the three 24v output terminals labeled S1,S2,S3
SIZING HOT WATER
Hot Water Coil If we have: 120F EWT 6 GPM 600 CFM Output is 28,200 BTU s To protect the motor (which is in the air stream, do not use above 150F entering water temperature EWT)
Unico and Hot Water Heat
Thermostat Block
Accessory Terminals
Condenser Terminals Anti-Frost Switch
LED Lights Unico Presentation Default Settings
Standard Blower Will require an add on relay such as TACO SR-571 in order to turn the pump or boiler on when calling for heating
INSTALLING AN ELECTRIC DUCT HEATER Now mounts directly to the blower module In the past UL requirements made us put this four feet downstream from the air handler
Electric Duct Heater
Electric Furnace Installed
Electric Duct Heaters
O or B Valve Energized Use Defrost Wire
Isolation Relay (Uses Factory Relay) Used on New Heat Pumps that have feedback on O in defrost
Conclusion Unico is the premier choice for BOTH heating and cooling Can be used as supplemental heating or as a stand-alone system Heating capacities up to 150,000 btu s output (per system) The iseries is a revolutionary way to provide heating with Unico
