ProMIX™ 101 Radiant
Heating Reset Control

Installation
1. Mount the control on a wall near the
modulating valve.
2. The outdoor air sensor should be mounted
in a shady location, preferably on the
north side of the building under the eaves
or a window sill. Drill a
¹⁄₄
" hole through
the wall and caulk the sensor in place so it
is not in contact with the wall.
3. The primary loop (or boiler return) sensor
and the secondary (or radiant) supply
sensor should be installed in wells if
possible. If installed in wells, a heat
conductive paste should be used to
eliminate the air space with in the well, to
improve thermal transfer to the sensor. If
wells are not used, tape the sensor se-
curely to a metal pipe using aluminum
tape. Cover with at least 1" thick insula-
tion, extending 2" beyond each end of the
sensor. Any additional wiring required to
connect a sensor to the ProMIX™ control
panel should be run with 18-22 AWG wire.
4. Wire the control as indicated by the termi-
nal block labels or by the wiring schematic
provided in Section 6. Be sure to provide
an earth ground to the case.
5. The ProMIX™ 101 Controller comes with
adjustable jumper settings set to operate
in Fahrenheit temperature, direct acting
and 0 - 10v modes. If settings are required
other than the preset values, move the
jumper (s) to the proper position. See
chart below.
6. Set the design temperature knobs to the
appropriate temperatures. The tempera-
ture setting can be fine tuned in the Power
Up/Setup Display Sequence.
7. Turn on the 120VAC supply.
8. Hold the Display Button and press the
Test/Reset button to enter the test mode.
9. Press the Display button repeatedly to test
the inputs and outputs, and to fine-tune
the temperature setting inputted in step 6.
10. Install the cover.
NOTE:
Make sure sensor wires are routed
away from motors, relays and other high voltage
wiring in order to avoid erratic temperature
readings due to noisy electronic environments.
Attach the shields to the grounded case using
the mounting screw near the sensor terminals.
