The MPC Platinum is able to maintain two different heat levels. The Day heat level is the higher level of heat. It provides
comfortable temperatures when the building tenants are active. The Night heat level provides lower heat and conserves energy when
the building is empty or when tenants are asleep. Both heat levels rely on the identical cycle concept, but the lower Night settings
provide less heat given the same outdoor temperature.
SEQUENCE OF OPERATION
• The MPC Platinum activates the steam source when the outside temperature falls below the outdoor sensor cutoff (factory set at
55°F for Day and 40°F for Night, but fully adjustable).
• The MPC Platinum will continue to call for heat, keeping the steam source active, until the heating system sensor reaches its
adjustable Set Point. This indicates that steam has gotten entirely through the system, or that "heat is established".
• Once "heat is established", the Cycle-ON segment of the cycle will begin.
• During the Cycle-ON period, the MPC Platinum will keep the steam source activated. The length of the ON part of the cycle
is dependent on the outdoor temperature, the Day/Night setting, and several user selectable adjustments that can be tuned to the
specic heat loss characteristics of the building.
• Once the Cycle-ON part has ended, the Cycle-OFF part of the cycle will begin. The MPC Platinum will turn off the boiler or
close the steam valve for the remainder of this cycle.
• When the Cycle-OFF part is over, the MPC Platinum will once again activate the steam source unless either the outside
temperature has risen above the cuttoff, or the thermal lockout is active.
• With the thermal lockout, the heating system sensor temperature must fall below the Set Point through an adjustable differential
before the heating source can be reactivated. This allows residual heat in the pipes to continue to heat the building. Once the
pipes have cooled sufciently, a new cycle can begin.
• However, if the MPC Platinum is an Internet capable control and space sensors are installed, the control checks for Space Lockout
before staring another cycle.
