OPERATION
T7200/T7300 Relay Logic
The T7200/T7300 contains three switching relays. In
conventional applications, the relays control first stage cooling,
first stage heating, and fan. In heat pump applications, the
relays control the heat pump compressor, auxiliary heat, and
the fan. Because of this change in switching logic, it is
important to use Q7300C,D Subbases when the T7300 is set
for heat pump applications and the Q7300A,G Subbases when
the T7300 is set for conventional applications.
The T7200D Relay Logic is for conventional applications. The
T7200E Relay Logic is for heat pump applications.
T7200/T7300 and Conventional Thermostats
P+I Control
The T7200/T7300 microprocessor based control requires that
the user understands temperature control and thermostat
performance. A conventional electromechanical or electronic
thermostat does not control temperature precisely at setpoint.
Typically, there is an offset (droop) in the control point as the
system load changes. This is a phenomenon that most
people in the industry know and accept. Many factors
contribute to offset including switch differential, thermal lag,
overshoot, cycle rates and system load.
The thermostat microprocessor simultaneously gathers,
compares and computes data. Using this data, it controls a
wide variety of functions. The special proprietary algorithm
(program) in the thermostat eliminates the factors causing
