Abstract:
A method of controlling a transport temperature control unit to maintain a first conditioned space within a transport at a temperature setpoint, the temperature control unit having cooling and heating cycles for cooling and heating the conditioned space, the temperature control unit including a first programmable temperature range, the transport further comprising a second conditioned space and the unit further comprising a second programmable temperature range, the method comprising:programming into the unit a first pre-programmed control mode for maintaining the temperature setpoint; configuring the unit such that a second control mode for maintaining the temperature setpoint is programmable into the unit by an end user; selecting numerical temperature values for the first programmable temperature range, the selection of numerical values being made by the end user; selecting the first pre-programmed control mode for operation of the first programmable temperature range or to program the second control mode into the unit for operation of the first programmable temperature range, the selection of the first pre-programmed or to program the second control mode being made by the end user; programming the second control mode into the first programmable temperature range by the end user when the second control mode is desired by the end user; utilizing one of the first pre-programmed control mode and the second control mode to control the operation of the unit in the second conditioned space with the second programmable temperature range; and selecting a first priority for the first programmable temperature range and a second priority for the second programmable temperature range by the end user.
