1. Disconnect power before servicing.
2. See nameplate for correct voltage. Use 75 C minimum copper
conductors only. Unit terminals are not designed to accept any
other wiring.
3. Motor(s) is thermally protected. Units with 2 motors are wired
parallel.

In winter, the system is switched over to hot water and requires 2 auto changeover devices (aquastats). One device controls the switching of the thermostat, the other device locks out
the electric heater when hot water is in the coil.
With this system, the fan runs continuously unless manually
switched to the OFF position. Fan must be on before thermostat can send signal to open chilled water valve or turn on electric heater.
Two control methods are available:
1. Use of a standard automatic changeover thermostat
with a deadband between heating and cooling.
2. Use of a manual changeover thermostat. Only one
changeover is required with this method.
A 2-way or 3-way electric valve must be included with this
system.
OPERATION
Manual Fan Control — The standard fan-speed switch
is furnished unit-mounted and wired on all vertical cabinet
units. On all vertical furred-in units and all horizontal units, the
switch is shipped separately on a decorative wall plate for field
mounting and wiring.
The standard switch has LOW, MEDIUM, HIGH and OFF
positions plus an auxiliary contact to energize thermostats,
valves, dampers, etc.
Thermostatic Fan Control, 2-Pipe Systems —
The thermostat cycles the fan on and off from any selected
speed setting to maintain selected room temperature. Controls
can be wired for heating-only, cooling-only or for heating/
cooling with the addition of an automatic changeover device
that senses water temperature and changes the action of the
thermostat as required.
Thermostat 2-Pipe Total Electric Heat with
Valve Control — With this system, the complete heating
Thermostatic Fan Control, 2-Pipe Systems
with Safety Cycle — This control is used for high
requirement for the space is provided by the electric heater; the
water system is never changed over for heating. It is therefore
possible, just as with 4-pipe systems, to have heating or cooling
at any time of the year.
The fan runs continuously unless it is manually switched to
the OFF position. Fan must be on before thermostat can send
signal to open chilled water valve or turn on electric heater.
Normally, an automatic changeover thermostat with a
deadband between heating and cooling is used, but a manual
changeover thermostat is also suitable. A 2-way or 3-way valve
must also be used so that the chilled water is off whenever the
heater is on. No changeover device to sense water temperature
is necessary.
humidity situations in which condensate problems can occur if
fan is turned off while chilled water is still running through the
coil.
The wiring provides fan cycling from HIGH to LOW on the
cooling cycle and from LOW to OFF on the heating cycle. An
ON-OFF toggle switch replaces the standard 3-speed fan
switch. The toggle switch can be concealed to ensure that the
unit runs on low speed when cooling. This action greatly
reduces the chance of condensation problems that exist with
other standard fan cycling controls.
Thermostatic Electric Valve Control, 2-Pipe —
A thermostatically controlled 2-position valve provides
superior control to fan cycling. With this control, the fan runs
continuously unless it is manually switched to the OFF
position. The fan must be on before the valve can be opened to
supply water to the coil.
This system can be used for normal 2-pipe changeover
systems and can also be furnished for cooling-only or heatingonly applications by omitting the changeover and specifying
which application is intended.
Thermostatic Valve Control, 4-Pipe — The 4-pipe
system provides the ultimate in economy and room temperature control. Both hot water and chilled water are available at
any time.
Normally an automatic changeover thermostat is used, but a
manual changeover thermostat is also suitable. Two 2-way
valves, two 3-way valves, or one 2-way plus one 3-way valve
must be selected. An automatic changeover device to sense
water temperature is not required.
With this system, the fan runs continuously unless it is
manually switched to the OFF position. The fan must be on
before thermostat can send a signal to open the chilled water or
hot water valve.
Thermostatic 2-Pipe Auxiliary Electric Heat
with Valve Control — This system, also called Twilight
or Intermediate Season electric heat, goes a long way towards
solving the spring and fall control problems of 2-pipe systems.
Chilled water can be available late into the fall. It may also
be turned on early in the spring and still provide heat to all units
when required.

**Only used with overflow switch.
NOTES:
1. This is a point-to-point electrical diagram.
2. Caution: Disconnect power before servicing.
3. See nameplate for correct voltage. Use 75 C minimum copper conductors only.
Unit terminals are not designed to accept any other wiring.
4. Blower motor(s) thermally protected.
5. To ensure proper fan interlock and sequencing, external controller must energize heater stages in numerical order shown and deenergize stages in reverse
order (first on, last off).
6. All contractor wiring must conform to electrical codes, national and local.
