2.5.1-  Anticipator  adjustment (if required) on thermostat 
equipped  with heat anticipator adjustment 

 

Some thermostats are equipped with a heat anticipator that must 
be adjusted according to the  instructions supplied.   This is  to 
ensure that the heating mode is comfortable and economical. 

 

Generally speaking, on a single stage thermostat, a reading of 
the current must be taken with an ammeter as follows: 

1.  Move  the  anticipator  to  its  highest  setting,  rendering  it 

ineffective. 

2.  Remove  the  wire  from the  W1  terminal and  connect  an 

ammeter between the terminal and the wire. 

3.  Call for heat by raising the set point on the thermostat and 

allow the furnace to run for 3 to 4 minutes to reach its peak 
output. 

4.  Once the current has stabilized, a reading should be taken 

and the anticipator adjusted to that value.  If longer heating 
cycles are desired, the anticipator can be set  to  a higher 
value 

2.5.2-  Air ducts 

The ducts  must be  sized such a  way as to  accommodate the 
specified airflow and the available static pressure.  Refer to the 
applicable local and/or national installation codes. 
 
Insulate  the  ducts  that  lead through non-heated areas.    Use 
flexible  supply  and  return  air  connectors  to  avoid  the 
transmission of vibration.  To make the unit run even quieter, the 
installer should: 

a.  Use two  elbows between each outlet and the supply and 

return air plenum; 

b.  Cover the vertical sections of the supply and return air duct 

with soundproofing material; 

c. 

Use baffles in short radius elbows; 

d.  Use flexible hangers to suspend the ducts. 

 
A heat pump or an air conditioner can be added to this furnace, 
in  either  the  supply  or  return  air  duct.    Carefully follow the 
instructions provided with  these  appliances to  ensure  proper 
installation and hook-up to the electric furnace.  Refrigerant and 
drainage pipes must  in no  way  hinder access  to  the  furnace 
panels. 

2.6-  SUPPLY AIR  ADJUSTMENTS 

Fan Control Board taps are used by the installer to configure a 
system.   The ECM motor uses the selected taps to  modify its 
operation to a pre-programmed table of airflows (Refer to Table 
3 and Table 4).  Airflows are based on system size or mode of 
operation  and  those  airflows  are  modified  in  response  to 
thermostat inputs such as dehumidification request. 
 
The U

NIQUE

 furnace must be configured to operate properly with 

system components with which it is installed.  To  successfully 
configure a  system  (see  information printed on  circuit  board 
label located next to select pins), move the 6 select wires to the 
pins which  match the  components used. (Refer  to  Figure 10 
below) 

 

Figure 10 : Fan Control Board 

 

2.6.1-  HEAT KW/CFM adjustment 

Installer  must  verify  (factory  set)  the  electric  heat  airflow 
adjustment required for kW size heater installed. 
 
The select pins are marked 25, 23/20, 18/15, 10 (for ½ HP ECM 
motor unit) and 30/27, 25, 23, 20, (for 1.0 HP ECM motor unit). 
Refer to the  unit wiring diagram and select the pin for the kW 
size heater being used (Refer to Figure 10 and Figure 16). 

 
The  airflow  must  be  large  enough  for  safe  and  continuous 
operation. (Refer to Table 3 and 4 for airflow delivery CFM).
