Application:
The ACCUSTAT® model ES-AH11 thermostat was
designed to operate 24VAC to 30VAC single stage heating and cooling
systems. This thermostat is MERCURY FREE!! The ACCUSTAT®
models utilize pre-set plug-in temperature setpoints to
activate the circuits. Room air temperature is measured by a micro-
processor and compared with the plug-in setpoint temperature. This
thermostat can operate in heat only, cool only or be off. The fan cycles
on/off with calls for heating or cooling or can be on continuously. The
thermostat has a locking cover to prevent tampering.
Operating Conditions:
The electronic mechanisms incorporated within this unit REQUIRE
operating conditions similar to other electronic devices intended for
INDOOR USE ONLY, 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. Air quality must be main-
tained, FREE of heavy dust or debris which may infiltrate the interior
of this device. Installation in any space which is unfinished or under-
going 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 styrene 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 TO OBSERVE ANY OF THEABOVE CONDITIONS OF USE
WILL COMPLETELY VOID THE SUPPLIER WARRANTY.
CAUTION
MAKE SURE UNIT IS PROPERLY CONNECTED. DAMAGE TO THE
CONTROL CAN BE CAUSED BY MISWIRING, WHICH WILL VOID
THE WARRANTY.

GENERAL INSTRUCTIONS:
This control should be installed and serviced by a qualified contractor.
1. Caution: Make sure that power to the control has been turned
off before doing any installing or service work. Class 2 transformers
can be damaged if a short circuit occurs when disconnecting wires
from the old thermostat.
2. All wiring must conform to local and state codes and ordinances.
3. A thorough check-out of the system must be made after the
control has been installed.
4. This thermostat was designed to operate as a energy harvesting.
control. A common wire is optional. If the thermostat is connected
directly to a logic board at the equipment, in order for it to function,
it may be necessary to connect a common to the thermostat and
turn off the energy harvesting switch.
MOUNTING THE CONTROL:
1. Open case as shown.
2. Choose a location about 5 feet above the floor, in an area where
there is good air circulation. Such an area will provide an average
room temperature.
3. Do NOT mount thermostat where it may be affected by drafts, hot
or cold air from ducts or radiant heat from the sun or appliances.
4. Pull thermostat cable through hole in wall or outlet box.
5. Plug wall hole to prevent drafts which may affect thermostat.
6. Use the screws supplied to mount the case on the wall.
7. This control is not position sensitive. However, heat rises and
some heating does occur in the control. It is recommended that
the unit be mounted with the top up.
INSTALLING PLUG-IN SETPOINTS:
Installing the pre-set plug-in temperature setpoints is as easy as
installing a fuse. Direction does not matter. The large plated tabs
must be pointed toward the thermostat. Press the plug-in setpoint
firmly into position.
NOTE: The plug-in setpoints must be installed at all times.
Removal of the setpoints will disable the thermostat.
NOTE: RC and RH are internally connected by J3 Jumper.
For dual transformer application cut and remove J3 Jumper.

Operating with a common wire connection:
If installing the thermostat with a common wire connection, place the
ENERGY HARVESTING switch in the OFF position. Upon first power
up or following a power failure the thermostat will run under normal
operating conditions within 5 minutes.
Operating without a common wire connection:
If installing the thermostat without a common wire connection, do the
following:
Prior to mounting the thermostat –
Place the ENERGY HARVESTING switch in the ON position.
At first power up or following a power failure it may take the thermostat
7 to 20 minutes for the power harvesting circuitry to charge before going
into the first heating or cooling call.
An optional method of bypassing the 7 to 20 minute wait is to connect
a 9V battery to the sensor board battery terminals.
LED D1 will light once the battery is connected.
When done charging the LED will become dim or go off (approximately
2 minutes).
Remove battery and the thermostat will run under normal operating
conditions within 5 minutes.
While the battery is attached the unit may be tested as stated to the
right.
NOTE: The thermostat will not attempt to control temperature
until the battery is removed
IMPORTANT NOTICE TO INSTALLERS TESTING:
To place thermostat in test mode insert 9 volt battery into sensor
board battery terminals.
If storage capacitors are not charged a light will come on in the upper
right corner.
NOTE: To test, plug-in setpoints are required.
Prior to the test verify that your SW5 switch settings are set correctly
per your application.
Cooling:
C1 setpoint must be installed.
HEAT/OFF/COOL switch must be in the COOL position.
1. Press the “B” button.
Fan (G) and cooling (Y1) will turn on.
2. Press the “B” button again.
All outputs will turn off and cooling test is complete.
Proceed to heating test, if necessary, or remove battery to end
testing.
Heating:
H1 setpoint must be installed.
HEAT/OFF/COOL switch must be in the HEAT position.
1. Press the “C” button.
Heat (W1) will turn on.
If SW5 switch position 3 is ON (electric heat) fan (G) will also turn on.
2. Press the “C” button again.
All outputs will turn off and heating test is complete.
Proceed to cooling test, if necessary, or remove battery to end
testing.
