TEMPERATURE AND HUMIDITY PROGRAM CONTROLLER

摘要

PURPOSE:To perform both the setting of a program pattern and the control action by a unit of the controller, by performing a calculation through the CPU from the set memory contents and the input signal and then delivering a control signal according to the program pattern. CONSTITUTION:The dry-bulb and wet-bulb temperature input signals TD and TW are supplied to the input terminals 11 and 12; and the remote dry-bulb and wet-bulb set input signals TSD and TSW (or the relative humidity input signal TRH) are supplied to the input signals 13 and 14 respectively. These signals receive an A/D conversion 3 via the input switch 2. The setter 4 sets the program patterns of both the dry-bulb temperature value TD' and the relative humidity value TRH' and then stores the set contents into the memory device 7. According to this memory contents and the input signal, the CPU6 perform an operation to deliver a control signal according to the program pattern.
