EW Series Hydronic units can be used in a variety of applica-

tions including domestic hot water, radiant floor heating, pool/

spa heating, fan coils, and even snow melt. 

A sophisticated microprocessor controls the pumps and 

compressor by sampling water temperatures even during “off” 

cycles.  The controller enables the user to view all modes of 

operation and easily adjust setpoint temperatures. This control 

has a wide range of set-up flexibility to meet the variety of ap-

plications in which the unit can be installed. However, configu-

ration of the control is done only at the time of installation as 

it requires special codes and a thorough understanding of the 

application and the control sequence. 

Generally, the unit will be set and controlled automatically to 

provide the correct temperature water. However, you can view 

the setpoint, by pressing the ▲ or ▼ arrow once (the display 

on the control panel will begin flashing). Subsequent presses 

of either the ▲ or ▼ arrow will change the setpoint by one 

degree. 

In addition to the water temperature display, the control panel 

also has 6 LED indicators that indicate when the unit is in one 

of the following modes: Lockout, Standby, Primary, Heating, 

Cooling, or Secondary Mode. To change modes, press the 

mode button. 

To protect the unit, the control monitors functions and conditions within the system. In the event of a failure or 

unsafe condition, the unit will go into Lockout mode. During lockout mode, the display will flash the lockout code cor-

responding to the fault condition. The compressor, pumps, and secondary output are de-energized. Lockout modes 

of any kind can be reset by pressing the mode button twice. Turning off the unit’s breaker (and then back on after 

60 seconds) also resets the lockout. Do not repeatedly reset the lockout. Doing so could damage the unit or other 

components in the system. Contact your dealer to resolve the problem. 

EW units include Scroll compressors and R-410A refrigerant for exceptional efficiency and performance. These 

units are ENERGY STAR® qualified and safety certified by ETL.
