WLCA/WLHA High Wall Evaporator

24

Heat Pump with Electric Heat:

Select  a  thermostat  that  is  compatible 

with  a  single  stage  cooling,  two-stage 

heat, heat pump system. The thermostat 

should  have  “R”,  “Y”,  “O”,  “W  (or  W2)” 

and  “G”  terminals.  The  thermostat  may 

also have a “C” terminal. If the indoor unit 

is not equipped with electric heat then a 

single stage heat pump thermostat is ad

-

equate.

Fan Operation

The indoor unit utilizes a two-speed mo

-

tor. The FAN button will allow the selection 

of the desired fan speed setting (High or 

Low). The wall thermostat will control the 

call for fan operation (On or Off) through 

the low volt terminals “R” and “G”.

After the room thermostat has been sat

-

isfied  and  the  call  for  fan  has  been  re

-

moved,  the  indoor  fan  to  remain  on  for 

an additional 60 seconds. This increases 

efficiency by pulling the remaining energy 

from the unit.

 

Some  thermostats  are  equipped  with  an 

“AUTO/ON” fan switch. When this switch 

is  placed  in  the  “ON”  position  the  indoor 

fan  will  run  continuous.  When  the  switch 

is in the “AUTO” position the indoor fan will 

cycle with the call for heating or cooling. 

Cooling operation:

The wall thermostat will control the call for 

cooling operation (On or Off) through the 

low volt terminals “R” and “Y”. After con

-

necting  the  thermostat  to  the  unit,  place 

the  system  switch  in  Cool  mode. Adjust 

the set-point temperature below the room 

temperature.  The  compressor  and  fan 

motors  will  start  and  cooling  will  begin. 

Next,  place  the  set-point  temperature 

above the room temperature. The outdoor 

condenser will stop. The fan will operate 

as described in Fan Operation.

Note:

 

Once the cooling has cycled off 

or following a power outage, the com

-

pressor will not start for at least three 

minutes (See Short Cycle Protection).

Electric heat operation:

For  remote  thermostat  operation  with 

electric  heat  the  control  must  first  be 

configured properly (Remote – ON, Heat 

source – “ON”). See: Configuration Inter

-

face mode.

 

The wall thermostat will control the call for 

electric heat operation (On or Off) through 

the low volt terminals “R” and “W”. After 

connecting  the  thermostat  to  unit,  place 

the  system  switch  in  Heat  mode. Adjust 

the set-point temperature above the room 

temperature. The  electric  heat  will  ener

-

gize along with the indoor fan motor. Heat

-

ing will continue so long as the set-point 

remains  above  room  temperature.  Next, 

place  the  set-point  temperature  below 

room temperature. The Electric heater will 

switch off and the indoor fan will remain 

on for an additional sixty seconds.

Note:

 

Once the heating has cycled off 

or following a power outage, the heat

-

ing  will  not  resume  for  at  least  three 

minutes (See Short Cycle Protection).

Optional  Heat  Pump  With  Electric 

Heat 

(2-stage heating):

For  remote  thermostat  operation  for  two 

stage  heating  including  a  heat  pump 

condenser  and  indoor  electric  heat,  the 

control  must  first  be  configured  properly 

(Remote – ON, Heat source – “ON”). See: 

Configuration Interface mode.

 

The wall thermostat will control the call for 

electric heat operation (On or Off) through 

the  low

  Volt  terminals  “R”  and  “W”  for 

compressor (heat pump) heating through 

terminals “R” and “Y”. After connecting the 

two stage heating thermostat to the unit,
