 Module
3 shows what control
technologies are available to make sure that energy
consuming equipment is on only when needed. It also shows how
to program a programmable thermostat.
Similar in size and build to the other modules, Module 3 is a tabletop
module with various control technologies attached:
- Photocell
- Motion
Sensor
- 24-hour
Timer
- Twist-timer
These
control systems are attached to a lamp that turns on and off based on
what is sensed.
Module
3 also houses four identical and working programmable
thermostats. Next to each programmable thermostat,
there is a push-button switch connected to a multi-colored
lamp. The programmable thermostat selected for this exercise
is a very common thermostat found in 60-70% of schools and
homes. A large diagram is attached to the module to show how
to program these thermostats.
Another
exhibit available on this module is a Past-Present-Future thermostat
model. A manually controlled dial thermostat represents the
type of thermostat used in the past. A programmable
thermostat represents the type of thermostat in the present, and a
remotely controlled thermostat (controlled from a remote station or
through the internet)
represents how thermostats will advance in the
future.
This
exhibit is designed to illustrate the
technological evolution of
thermostats, and how thermostats are becoming more
sophisticated
and
practical at the same time.
