The MP 2 is capable of controlling the supply water tempera- ture for up to nine ON / OFF stages based on out door tem- perature, control for the Domestic Hot W ater (DHW) gener- ation, a set point requirement or optionally an external input signal (0 - 10 V (dc)).
This instruction manual is organized into four main sections: 1) Sequence of Operation, 2) Installation, 3) Control Settings, and 4) T esting and T roubleshooting.

The following defined terms and symbols are used through- out this manual to bring attention to the presence of hazards of various risk levels, or to bring attention to important infor- mation concerning the life of the product, see Figure 4 below .
C OMBUSTION A IR OR A LARM C ONT ACT The control has an isolated contact that can be used as either a combustion air damper contact or an alarm cont act. This selection is made using the C. A. / Alarm DIP switch. Combustion Air (C. A.) When the DIP switch is set to C.
Resetting the Rot ation Sequence T o reset the rotation sequence, set the Rotate / Of f DIP switch to the Off setting for 5 seconds and then return the DIP switch to the Rotate setting. R UNNING T IMES The control displays the accumulated running time of each boiler in the VIEW menu.
L O / H IO R L O / L O When using multi-stage boilers, a selection must be made regarding the staging order of the boiler(s). This adjustment is made in the ADJUST menu of the control. Lo / Hi If the Lo/Hi staging option is selected the control st ages in sequence all of the stages in a single boiler .
S T AGE D ELA Y The stage delay is the minimum time delay between the fir- ing of stages. After this delay has expired the control can fire the next stage if it is required.
B OILER P UMP O PERA TION In certain modes of operation, the control can operate the individual boiler pumps on each boiler in addition to the pri- mary pump. The boiler pump turns on prior to the boiler fir- ing and continues to run after the boiler is turned of f.
type of terminal unit. This improves the control of the air temperature in the building. B OILER I NDOOR D ESIGN T EMPERA TURE The indoor design temperature is the room temperature that was used in the original heat loss calculations for the build- ing.
H IGH M ASS R ADIANT (1) This type of a hydronic radiant floor is embedded in either a thick concrete or gypsumpour . This heating system has a large thermal mass and is slow acting (FIG .
SECTION E: DOMESTIC HOT W A TER OPERA- TION S ECTION E1: D OMESTIC H OT W A TER (DHW) DHW D EMAND A DHW Demand is required for the control to provide heat to the DHW system. A DHW aquastat or set point control is used as a switch in the DHW demand circuit.
DHW M ODE 4 - DHW IN P RIMARY / S ECONDAR Y WITH P RIORITY When a DHW Demand is present, the Relay 9 / DHW con- tact (terminals 30 and 31) is closed and the primary pump contact is closed.
N UMBER OF B OILERS U SED F OR DHW G ENERA TION The number of boilers used for DHW generation can be selected from one to the maximum number of boilers using the BOIL DHW setting. This applies when only a DHW Demand is present. If there are other demands present, the control does not limit the number of boilers operated.
B OILER T ARGET D URING S ET P OINT The boiler target temperature during a set point demand is increased to at least the Set Point setting. This temperature is maintained as long as the control has a set point demand.
I NPUT S IGNAL The control can accept either a 0 - 10 V (dc) signal or a 2 - 10 V (dc) signal. The External Input Signal setting must be set to the proper setting based on the signal that is being sent to the control.

Set Point Demand T o generate a setpoint demand, a voltage between 24 V (ac) and 230 V (ac) must be applied across the Setp / DHW and Com Dem terminals (8 and 7) (FIG .
Relay 9 / DHW If a DHW pump or DHW valve is connected to the Relay 9 / DHW contact (30 and 31) (FIG . 30), make sure the power to the pump or valve circuit is off and inst all a jumper between those terminals. When the DHW circuit is powered up, the DHW pump should turn on or the DHW valve should open completely .
A good quality electrical test meter , capable of reading from at least 0 - 300 V (ac) and at least 0 - 2,000,000 ohm, is essential to properly test the wiring and sensors. T EST T HE S ENSORS In order to test the sensors, the actual temperature at each sensor location must be measured.
T EST T HE O UTPUTS Primary Pump (Prim P1) If a primary pump is connected to the Prim P1 terminal (1 1), make sure that power to the terminal block is off and inst all a jumper between the Power L and Prim P1 terminals (10 and 1 1) (FIG . 37). When power is applied to the Power N and Power L terminals (9 and 10) (FIG .
C ONNECTING T HE C ONTROL Make sure all power to the devices and terminal blocks is off, and remove any remaining jumpers from the terminals. Reconnect the terminal blocks to the control by carefully aligning them with their respective headers on the control, and then pushing the terminal blocks into the headers.
The Alarm / C.A. DIP switch selects whether a combustion air damper or alarm device is to be connected to the C.A. / Alarm terminals (12 and 13) (FIG . 45). R O TAT E / O FF The Rotate / Of f DIP switch selects whether or not the con- trol is to provide Equal Run T ime Rotation of the boiler stages.

The control has a built-in test routine that is used to test the main control functions. The control continually monitors the sensors and displays an error message whenever a fault is found. See the following pages for a list of the control’ s error messages and possible causes.
The control was unable to read a piece of information stored in its memory (FIG . 53). Because of this, the control was required to reload the factory settings into all of the items in the ADJUST menu. The control will stop operation until all of the items in the ADJUST menu of the control have been checked by the user or installer .
The control is no longer able to read the boiler return sen- sor due to an open circuit (FIG . 59). The control will contin- ue to operate normally . Locate and repair the problem as described in INS7141. T o clear the error message from the control after the sensor has been rep aired, press either the Menu or Item button.
