Application:
This thermostat is a 24 volt heating and cooling digital temperature
control designed to operate 2 or 4-pipe fan coil systems. Switching
of load circuits is through relay contacts. Fan outputs can be
configured to operate 3, 2 or single speed fan motors. The fan control
also has configurations for user select fan speed with economy
function, continuous fan or auto cycle fan. This thermostat operates
on a single setpoint with automatic changeover from heating to cooling.
Installation Notice:
This high performance digital thermostat is designed to provide many
years of superior comfort control when properly installed and maintained.
To achieve maximum performance, this device is designed to draw
room air into itself continuously. Reasonable care must therefore be
taken with regard to air quality at the time of installation as well as
during periods of normal use, see operating conditions below.
Operating Conditions:
The electronic mechanisms incorporated within this unit REQUIRE
operating conditions similar to other electronic devices intended for
INDOOR USE ONL Y, such as would be acceptable for TV and similar
household appliances. Relative humidity must be less than 95% and
the atmosphere must be non-condensing. For operation in bathrooms,
shower or pool areas, outdoor entry ways, greenhouses and similar
applications, order the “-k” option. This product includes protection
for coastal/tropical application, therefore it is suitable for use in high
humidity environments. Air quality must be maintained FREE of heavy
dust or debris which may infiltrate the interior of this device. Installation
in any space which is unfinished or undergoing repainting or general
rehabilitation is also considered product abuse. This device should be
removed from service during any local construction activity.
Cleaning:
This device incorporates a high impact polycarbonate enclosure which
is easily cleaned with a dry cloth or vacuum brush. Occasional soiling
may be cleaned with a soft cloth lightly dampened with water and/or
mild cleaning solution. IN NO CASE should this device be directly
sprayed with or exposed to free flowing liquids, including water, which
could penetrate its interior.
FAILURE T O OBSER VE ANY OF THE ABOVE CONDITIONS OF USE
WILL COMPLETELY VOID THE SUPPLIER WARRANTY.
CAUTION
MAKE SURE UNIT IS PROPERLY CONNECTED. DAMAGE TO THE
DIGIT AL CONTROL CAN BE CAUSED BY MISWIRING, WHICH WILL
VOID THE WARRANTY. FOR SAFETY REASONS ALWAYS USE
WIRE NUTS ON ALL WIRE CONNECTIONS!!!

4-PIPE FAN COIL, 2-PIPE ELECTRIC HEAT OR
ELECTRONIC AQUASTAT INSTALLATION:
This device should be installed and serviced by a qualified technician.
Junction box mounting is highly recommended.
1. Caution: Make sure that power has been disconnected.
2. All wiring must comply with applicable codes and ordinances.
3. A thorough check-out of the system should be made after
installation is complete.
4. If fan motor is larger than 1/4 HP and/or electric heaters are used
for heating, additional power relays will be required
5. If retrofitting old thermostat, remove old thermostat from the
junction box, carefully noting the wire connections on the old unit.
Record wire color and terminal legends in spaces provided.

See mounting detail to the right.
Note: If application involves a
double ganged junction box,
Screw: 6/32 x 3/4"

a backplate will be required for a
complete installation.
Please consult your supplier.
User Note: The top of this unit will become warm to the touch. This is a
normal operation. Internal heating is employed to continuously convect
air upward through the thermostat, thereby improving room air temperature
measurement. Direct conflict with a downward ceiling fan or system fan air
flow may result in false temperature reading. Locate thermostat to avoid
interference.

Remote Sensor/Aquastat Option:
The remote sensor option features a dual mode external sensor
function. SEN2 is to be used only as a room temperature sensor
(order PSG P-RS). SEN3 is to be used only with the Electronic
Aquastat Kit (order PSG P-AK). The REF terminal is common to
both sensor inputs. To activate the SEN2 or SEN3 terminals see
programming instructions. Both sensor functions may be used at
the same time, having both electronic aquastat and remote room
temperature capability. When the remote sensor is connected, it
may be used to control the thermostat instead of the on board
sensor or it may be averaged with the on board sensor. Use only
3 conductor cable or shielded 2 conductor cable. Connect the
shield or the third wire to the COM terminal.
Remote Sensor
Terminal Block
Remote Setback
Terminal Block
Remote Setback/Shutdown Option:
The remote setback features a dual mode function. SB1 is the input
for remote setback (economy) and SB2 is the input for remote
shutdown mode. Setback mode when energized will remotely
place the thermostat in economy mode using the programmable
economy heat and cool setpoints. Shutdown mode when energized
will remotely place the thermostat in disable mode. The thermostat,
at this time, will not call for heating or cooling until taken out of shutdown mode.
To activate the setback or shutdown mode use dry contacts (relays
or mechanical switch) to connect the +3V terminal to the appropriate
SB1 or SB2 terminal. An open circuit on SB1 or SB2 will disable the
remote function.
A COM terminal is provided for active type remote switch gear such
as the electronic motion sensor. Do not use the COM terminal for
any other application.
Aquastat Sensor
IMPORTANT:
The electronic aquastat sensor replaces the bimetal switch
which is common in most 2-pipe heat/cool fan coil systems.
This allows for the thermostat to directly control the equipment
as well as provide for alterations in change-over temperature
thresholds. Follow the standard 4-pipe wiring diagram. Cool
wire will control the heat/cool valve, the heat wire will operate
as an auxilliary electric heat switch (depending on fan coil
equipment).
Isolate all of the unused wires.
Water
Main
Mount the Electronic Aquastat Sensor to the water pipe. The best
location is to be as close to the main pipe as possible and attached
before the water valve connection.

Refer to the programming instructions for selecting the aquastat
sensor function, temperature changeover settings, output configurations,
purge frequency and purge time duration. The thermostat will monitor
pipe temperature every 5 seconds. For a valvelss systems, select
the 2Pn configuration setting since this will bypass the valve purge
functions and provide heating or cooling based on pipe temperature
alone.
The 2PS and 2PE configurations operate with a valve purge function
to prevent incorrect temperature readings from static or standing water
in the pipe. The valve purge operates on a programmed interval
(purge frequency) for a programed duration (purge time duration)
in the event of low activity over an extended period of time.
If the heat or cool call has lasted for more than three minutes, the
pipe temperature heat or cool mode is rechecked to verify proper
operating mode.
