Setting the Over-Temperature
Thermostat
After the unit has reached set point, rotate the over-tem-
perature thermostat stem counterclockwise until the over-
temperature status lamp (4) is lit. Then rotate it clockwise
approximately 5 degrees past the point at which the lamp
is no longer lit. At this point, the over-temperature ther-
mostat will control heaters only at temperatures above the
controller set point.
Temperature Controller
1. CONTROLLER SELF-TEST: When the incuba-
tor is powered up the controller will display 8888
along with the three decimal points and the heat
ON indicator lamp. The display will then blank
out for 2 seconds before showing the chamber
temperature.
2. HEAT ON INDICATOR: The heat ON indicator
lamp is lit when the chamber heater is receiving
power. The lamp will normally flash when the
chamber temperature is at set point.
