What makes up a Unico System Understand What to Ask How to Place an Order

Sound Attenuator (UPC-26C) Outlet (UPC-56B) Elbow Plenum Blower Modules (2430,3642, 4860) Heating Module (MH2430, MH3660) Supply Tubing (UPC-25) Cooling Modules (MC2430, MC3642, MC4860) Return Air Adapter (UPC-59-xxxx) Secondary Drain Pan Sound Attenuator (UPC-26C) Return Air Duct (UPC-04-xxxx) Return Air Box (UPC-01-xxxx)

The Load What is Cooling/Heating Requirement Remember, a BTU is a BTU Unico has sizes from One to Five Tons of cooling Unico can provide up to 20 KW of electric heat Unico can provide up to 150,000 btu output of hot water heat

Sizing the Job Use the ACCA Manual “J” or ASHRAE equivalent A Load calculation is the same for Unico as for all other HVAC systems Unico provides a Bulletin 40-10 which contains a very simple sizing guide based on older building construction

Remember a Btu is still a Btu This is the CONTRACTOR’S responsibility Ask for the size in Tons Remember a Btu is still a Btu This is the CONTRACTOR’S responsibility Remember to let them know that we are the same as a conventional system when it comes to sizing

Unico Sizes M1218 M2430 M3036 M3642 M4860 1 to 1 ½ Tons 2 to 2 ½ Tons Explain a little bit about how we go about naming part numbers

Air Handler Position Vertical or Horizontal If Vertical: Order Vertical Stand Don’t order Return Air If Horizontal: Order Return Air Assembly Order Secondary Drain pan If horizontal is hard, ask “Attic Installation”?

The Unico Blower Module

Today we use an EC Blower Motor Features and Benefits The History of the Unico System Blower Module and Motor Today we use an EC Blower Motor

ECM … PSC Side by side comparison of the old PSC motor (on right) with the new ECM. Silver item at the bottom is the controller, these are very sensitive to high heat, therefore don’t use a hot water coil with entering water temperature of greater than 140 degrees

How does it work? Uses the Emerson EC motor, a very common industry motor The control for the motor is specific for the designs of the Unico system. Sets a constant CFM by adjusting the RPM to conform with the Unico System fan curve

New SMART Board

LED Lights Default Settings LED Lights: Power, indicated 24v supply; Heat, unit in heating mode, PCB Control, something on the board’s software is causing the fan to run. Fan: flashes long for 100 CFM, short for 50 CFM Default The preset speeds for all units, allows you to program without a computer

How to Connect Use a laptop to connect
