Procedure

Installation in boiler compartment

Fig 1, top view of original wiring. Red arrows indicate where the controller power cable

will be tapped. Green arrow points to brew water control thermostat. Blue arrow points

to steam temperature control thermostat.

1) There are two thermostats on top of the boiler. The one on the left with a red dot on top is

the brew water temperature control thermostat. The one on the right is for controlling the

steaming temperature. You need to remove the cable connectors on both side of brew

water temperature thermostat (connectors with red and gray cable). They need to be

connected to the output cable of SSR (after the RTD sensor installation). You also need

to remove this thermostat and move the steaming thermostat to its position. This is

because you need to mount the RTD sensor to the thermowell underneath the steam

temperature control thermostat. This thermowell is closer to the cold water inlet, and

results in better control. You need to use a small to medium sized flat head screw driver

to remove the screw. Be very careful to not let it drop into the gap below. A magnetized
