3.3 Thermostat Programming

3.3.1 A-Tech-1.1 (See Figure 14)

The A-Tech-1.1 is a programmable thermostat that

represents one of the most advanced, solid-state,

microcomputer temperature controllers available. The

A-Tech-1.1 programmable thermostat provides the

user with the following features: single stage cooling/

heating control, heat/cool/auto/off modes of operation,

continuous/auto fan, day/time clock, setback feature

(accomplished through programming) and tempera-

ture setpoint override. See control panel for additional

features.

The temperature setpoint can be overridden tempo-

rarily or for an extended period. It is recommended to

run the fan continuously especially during cooling

mode to enhance efficiency. The thermostat may also

be switched between Celsius and Fahrenheit.

The thermostat allows one program for Monday

through Friday and one program for Saturday and

Sunday. The thermostat has been programmed from

the factory and it is suggested that your personal

schedule be programmed. Complete the program

schedule chart provided before beginning program-
