Automatic Controls for Heating, Refrigeration, Air Conditioning, Appliances, Engines, Pumps and Air Compressors PENN HAS A COMPLETE LINE OF AUTOMATIC CONTROLS FOR YOUR NEEDS Combination fan and limit control for heating Oil burner stack switch for heating PEXfN "RIMSET" THERMOSTAT It reduces your inventory! It's easier to read ( It's simpler to install! Low pressure refrigeration control The "RIMSET" room thermostat can be used for 12 different cooling and heating jobs! It quickly "plugs" into any subbase ... inventory is reduced because you stock variables of the sub-base only. Thus, if cooling is added later to a heat ing installation . . . simply change sub- base and use the same tnermostat. Direct-acting gas valve for heating "RIMSET" has one of the largest, most easily read dials you've ever seen. The scale remains stationary as the rim is dialed for temperature setting. In stallation is simpler, too. Sub-base does not have to be perfectly level for ac curate operation. Use "RIMSET" and Penn controls for all cooling and heating jobs . . . also for commercial refrigeration. 300 Controls and Instruments letter PRINCETON, INDIANA Y fttC.
