Programming an LAE LTR-5 Digital Controller

Learn how to configure the LAE LTR-5 thermostat, which features a single relay and probe. For a PTC probe, use the LTR-5T; for an NTC probe, use the LTR-5C.
Unlike some other LAE controllers, there is no dedicated parameter to set the relay to a heating or refrigerating mode. This video explains how to use the hysteresis differential parameter to engage the relay for a heater or chiller.
It also looks at the some of the other common functions including the readout scale (to control whether to display a decimal point) and set point limits.
