Dehumidification of Fresh Air with DCV Control -- Infor-

mation flom ASHRAE indicates that the largest humidity load

on any zone is the flesh air introduced. For some applications,

a field-installed energy recovely unit can be added to reduce

the moisture content of file fiesh tfir being brought into the

building when the enthalpy is high. In most cases, the normal

heating and cooling processes are more than adequate to re-

move the humidity loads for most commerci_d applications.

If nonnal rooftop heating and cooling operation is not ade-

quate for the outdoor humidity level, an enel_y recovery unit

and/or a dehumidification option should be considered.

Step 14 --Install Humidistat for Optional

MoistureMi$er TM Package-- MoistureMi$er dehu-

midification package operation can be controlled by field in-

stallation of a Canier-approved humidistat. To install the humi-

distat perform the following procedure:

1.Locate humidistat on a solid interior wall in the condi-

tioned space. Location should be a well ventilated area to sense average humidity.

2.Route thermostat cable or equivalent single leads of col-

ored wire from Humidistat terminals through conduit in

unit to the low voltage connection on the 2-poleterminal strip (TB3) as shown in Fig. 43 and Fig. 44. See Fig. 45

for operation_d diagram.
