NOTE: Minimum/maximum limits are only for start-up conditions, and
are meant for bringing the space up to occupancy temperature. Units
are not designed to operate at the minimum/maximum conditions on
a regular basis. The operating limits are dependant upon three primary
factors: 1) water temperature, 2) return air temperature, and 3) ambient
temperature. When any of the factors are at the minimum or maximum
levels, the other two factors must be at the normal level for proper and
reliable unit operation.
