CPU:

Motorola or Toshiba 3150 Neuron processor, containing three eight-bit CPUs. Each Neuron has a unique 48-bit network identification number.

Memory Capacity:

64K ROM/PROM (6K reserved for network operations, 58K usable for control algorithm code).

512 bytes EEPROM.

2K RAM.

Specified Space Temperature Sensing Range:

45 to 99°F (7 to 37°C) with an allowable control setpoint range from 50 to 90°F (10 to 32°C) when initiated from the network and 55 to 85°F (13 to 29°C) when configured and connected to T7770 or T7560 Wall Modules.
