See
Cooling and 3-Stage Reheat on page 35
.
This
application operates the same except for using a hot
water valve instead of electric heating elements for
reheat (a
VEB-43/46 series valve in place of the REE-
5001 relay).
To retrofit a CTE-510x thermostat in an existing
installation with a different valve than a VEB-43/46
series, see the corresponding installation guide for
that valve and actuator.
AO1 controls airflow and AO2 controls the valve.
When there is a call for heat, the thermostat
modulates the hot water valve.

with a
CTE-5104 in the
