ABSTRACT:
A readout apparatus that can be carried in the shirt pocket of a technician. The readout apparatus is used to easily and quickly make a connection to a heating system via a data access port of the heating controls, especially in low light situations, without the need for cables or probes. A display enables a technician to determine information concerning the operational characteristics of the heating system control unit to obtain information concerning the operational characteristics of the heating system. Real time operational information concerning the operation of the heating system via its control unit such as well temperature, cad cell, and line voltage are provided. The apparatus is powered from the electrical power available at the data access port so that the apparatus does not require the use of batteries or need any external switching such as an on/off button.
