„ General
Models TY6800Z and TTY6800Z are insertion
thermostats applicable to control temperature (two-
position) for air in duct and liquid in tank or pipe.
„ Features
(1) Electric two-position control
The temperature sensing element, filled with
liquid, detects changing of temperature.
Model TY6800Z has a built-in microswitch,
TTY6800Z has two built-in microswitches. They
are applicable to heating or cooling control.
(2) Easy temperature setting and differential gap
adjustment
Temperature setpoint is easily set by the knob
in the front of the thermostat.
Model TY6800Z has the differential gap adjustment function to control equipment smoothly.
Each microswitch of Model TTY6800Z has the fixed differential gap. Difference between the two switches
is easily adjusted to enable suitable sequence control for the connected equipment.

- Page 12 AB-6600 • To wire between the microswitch and the screw terminals, lay the wires from the terminals to the microswitch though the bottom inside of the box. • Connect the wires to the screw terminals using the round screw terminals (M4 size) as shown in Figure 19. Note: If the wiring was done improperly, the terminal lugs or wires may interfere each other and the terminal cover cannot be attached.
- Page 13 AB-6600 „ Settings IMPORTANT • According to the thermal load, be careful to specify the differential gap so as not to cause huntings. Failure to do so might start and stop the devices frequently and cause device failure. • Specify the differential gap appropriately, not too wide. Failure to do so might cause contact failure.

Page 16: Operation Check
AB-6600 < Heating two-step control > Based on the heating control system shown in Figure 18. Example of wiring for heating two-step control, operation of Model TTY6800Z thermostat is described assuming the temperature setpoint: 50 °C, differential gap: 3 °C, differential between two switches: 8 °C. (1) When the temperature of the controlled target falls to 55 °C, that is setpoint (50 °C) plus the differential between two switches (8 °C) minus the differential gap (3 °C), the switch 2 works to close the terminal R2 and W2, and then the heater 1 starts. - Page 17 AB-6600 „ Maintenance WARNING If this product is connected to a system, be sure to implement safety measures.
