Blue Dial (Wiring)
The blue dial temperature settings have been selected to be repre-
sentative of outdoor air temperatures. The two blue wires running from
the simulator are typically connected to the input terminals of the
outdoor sensor of a tekmar control (see figure 3).
Red Dial (Wiring)
The red dial temperature settings have been selected to be repre-
sentative of boiler supply temperatures. The two red wires running
from the simulator are typically connected to the input terminals of the
supply sensor of a tekmar control (see figure 3).
Yellow Dial (Wiring)
The yellow dial temperature settings have been selected to be
representative of indoor feedback readings. The two yellow wires
running from the simulator are typically connected to the 10K Sen
input terminals of a tekmar control.

D 002
The tekmar 10K Temperature Simulator 002 can be used to test any tekmar control using 10K thermistor
sensors. With this simulator, checking control operation on a counter or in a boiler room is a simple process.
The simulator is also ideal for use at trade shows or product training schools to demonstrate the features and
operation of various tekmar controls. Up to three different sensors can be individually simulated using the
three separate rotary switches. The simulator is designed to provide sensor resistance values for a 10k

that use thermistor sensors with
a different resistance curve can-
not be tested correctly with this
simulator. (This includes all older
tekmar controls with 2K sensor
inputs.)

After connecting up the simulator and applying power to
the control being tested, simulation can begin. Using the
data brochure for the control being tested, select tem-
peratures from the simulator to verify the operation of the
control.
As an example, Figure 3 shows a One Stage Boiler
Control 250 being tested. The following are typical
features you can test with the simulator — WWSD, Boiler
Minimum, Boiler Differential and Heating Curve. Some
calculations may be required to determine if correct con-
trol operation is taking place.
Note: Understanding the operation of the control
being tested is required to ensure correct conclu-
sions are made. Do not apply power to the simulator
as damage to the simulator may result.
