All models
– ECM™ blower motor, setup selection of four cooling sizes, 50% continuous air (fan – on
setting). High efficient air circulation at about 50-watt.
H
= Full WarmFlo capability with outdoor sensor. This provides warm air outlet temperature dial
selection and supply air ramp up with the decrease of outdoor temperature. This WarmFlo
feature definitely applies to heat pumps, but it is also the top of the line comfort for straight
electric, with air conditioning. The warm air dial suggested setting is 96° or 100° and the front
dial selects the rate of ramp up or temperature increase based upon outdoor. The “C” setting
will provide 114° warm air at 0° or 125° at -20° F outside. The ECM™ blower also ramps up
in speed as there is an increase in supply temperature or decrease in outdoor temperature.
Depending upon setup selection, the moderate heating blower speed could be as low as 60% of
full capacity and full capacity blower is only used below 15° outdoor.
Heat/cool conventional or basic heat pump room thermostat can apply.
A
= WarmFlo element modulation based upon a warm air set point and duct sensor. Heating blower
speed is installation setup per kW size. A higher CFM selection can be made if there is a desire
to “work” WarmFlo harder.
Heat/cool conventional thermostat applies.
E
= Non-WarmFlo, 10, 15, or 20 kW built-in strip heat, direct function of roomstat W. Setup
selection determines nominal ECM™ motor speed. A thermostat “E” type function could be
used to jump to full speed.
N =
Cabinet only, no electric elements or WarmFlo. This could typically be associated with an inlet
hydronics water coil. Control board includes a relay for pump, initiated with input W. Setup
selection determines heating blower speed. Cooling speeds and air conditioning interface are
the same as mentioned above.
Note
: Two-speed and multi-function room thermostat can also be configured with this system by adding
WF-HP2 interface controller.
