See Cooling with 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 retrot a CTE-510x thermostat in an existing
installation with a dierent valve than a VEB-43/46
series, see the corresponding installation guide for
that valve and actuator.
AO1 controls airow and AO2 controls the valve.
When there is a call for heat, the thermostat
modulates the hot water valve.
(See also the Cooling with Hot Water Reheat section
with a CTE-5104 in the CSP-5001/5002 Applications
Guide.)
NOTE: See also the use of the CTE-5202 with
discontinued VEP-12/22/34 series valves in
Cooling with Hot Water Reheat on page
