RT and RT Deviation – the hot product temperature can be measured by a single or dual RTD. For the dual RTD, the primary
input is always the one displayed as ‘Hot Product’.
The secondary RTD enables a self-check facility which can be used to maintain the integrity of primary and secondary
resistance thermometer devices. Any imbalance between the first and second RTD greater than the trip level entered in the
appropriate scroll automatically causes the flow to divert, regardless of the primary temperature measurement.

SINGLE – One divert set point can be set.
Divert Number
Select the divert setting required:
1, 2, 3, 4, 5, 6, 7 or 8 (used with associated
Divert Set Point, Hot Water Set Temperature
and Set Point Source displays).
Caution. Do not change divert numbers during a process (only before or after).
Operator Level (Enable Divert Number Selection)
Allows the divert number to be selected at Operator level.
