Wired a TA4 for on/off. PID functions are all Off. oUd is set to cool. Therefore, if PV is higher than SV, out1 light is on. Using a SS relay input of 2.5 to 30. Output 120 vac. However, the input reading on the relay using a meter is 1. No reading on the output side of the relay. Any ideas would be helpful. Thank you. Using a light as a load when cooling is called for. Out1 is lit also.
