GREYSTONE TLOSF24X01 TLOS Series Outside Low Limit Thermostat Instruction Manual
WIRING
•
•
Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent electrical shock or equipment damage.
Use 14-22 AWG shielded wiring for all connections and do not locate the device wires in the same conduit with wiring used to supply inductive loads such as
motors. Make all connections in accordance with national and local codes.
•
•
The temperature thermostat comes with the temperature sensor pre-wired to the PCB. If removal is required for installation then it may be re-wired as shown
in Figure 5.
Pull at least six inches of control wire into the enclosure, then complete the wiring connection according to the wire diagram for the applicable power supply
as shown in Figure 6.
•
•
Connect the DC positive or the AC voltage hot side to the PWR terminal. The supply common is connected to the COM terminal. See Figure 6.
The relay has both Normally Open (NO) and Normally Closed (NC) contacts available. The relay output is available on the NO/COM/NC terminal. Make
connections before applying power as shown in Figure 7.
•
•
•
The setpoint differential has 3 jumper selectable settings (Low/Mid/High). Set jumper to desired differential as shown in Figure 9.
To set the switching setpoint, turn the setpoint potentiometer to the desired temperature setting as shown in Figure 8.
Once all connections settings are made and checked, power can be applied.
