T8411R Electronic
Heat Pump Thermostat
The T8411R Heat Pump Thermostat provides 24V
control of two-stage heating and one-stage cooling heat
pump system with manual changeover from heat to cool.
First stage heating and cooling cycle rates are fixed at
3 cph. Second stage heating cycle rate is selectable at
3, 4, 5, 6, 9 or 12 cph. Temperature indication can be set
for °F or °C.
The T8411R Heat Pump Thermostat is powered directly
from the system transformer. Batteries are not required
because setpoints are held permanently by non-volatile
memory.
The T8411R includes a thermostat, wallplate (for wiring
and mounting thermostat), and owner’s guide. A 7 3/8 in.
x 5 3/4 in. (188mm x146 mm) decorator cover plate (for
covering wall marks) is available separately. Order
Honeywell part no. 209649A (taupe color).
