Cooling with Heating Changeover and Hot Water Reheat
See Cooling with Heating Changeover and Electric
Reheat on page 38. 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.
When there is hot air in the duct, changeover initi-
ates, allowing the heating signal from AO1 to control

is a call for heat, the thermostat modulates the hot
water valve.
NOTE: If using an existing TTE-2001 duct sensor/
transmier (instead of an STE-140x duct
sensor), connect to Terminals 1 and 2.
