Hardwired Or Communicated Space Sensor Control - Heating; Stand Alone Control - Cooling - York Eco 2 Quick Start Up Manual

HARDWIRED OR COMMUNICATED SPACE SENSOR
CONTROL – HEATING
Field Wiring
Connect the space sensor wiring to the fi eld wiring screw
connections on the Unit Controller (see Appendix 1).
Misc. Connections
Pneumatic tubing must be fi eld-supplied and installed
from the duct static transducer "high" side connection
to a fi eld supplied static pressure probe that is installed
approximately two-thirds down the trunk line in the
duct work. The duct static transducer is mounted in the
control compartment.
An atmospheric static pressure probe with a bracket is
factory supplied (shipped in the return section of the
unit) and is to be installed on the specifi ed support post
(see Appendix 1). A barbed fi tting is already factory
installed on the support post, and should be used to
connect the atmospheric probe using fi eld supplied
pneumatic tubing.
The black cap on the atmospheric
sensor probe should be positioned at
top. See Appendix 1 for details on the
installation of the probe.
