* Different than the boil timer in DSPR310D and JSL-73B. See section 5.7 in page 5 of manual of DSPR310D and section 7.2 of the manual of DSPR320.
** Advanced programming for DSPR320A: In mash mode, temp-control steps and power-control steps (boil steps) can be programmed. In boil mode, power-control steps and temp-control steps (mash steps) can be programmed. These two features can be useful for low-oxygen brewing and whirlpool methods. More relay features has been added for more complex taskes such as driving a chiller. See DSPR320A for details.
*** DSPR1 cannot read a temp sensor. DSPR120/300/220/400/310/320 can only read one PT100 RTD sensor.
