PRIMARY APPLIANCE CONTROL – is done utilizing the FMT 914 PCB as custom manufactured by SIT Controls of the
Netherlands for Hamilton Engineering, Inc.
POWER SUPPLY
In all scenarios shown below, 208 – 240 volt single phase power is connected to leads labeled Power L, Power L and
Ground. Appliance primary pump is wired to leads labeled Pump L, Pump L and Ground, pumps must be rated for 208v -
240v power supply. Maximum total allowable externally connected load to the FMT 914 is 550 watts.
SENSORS
Through the following pages you will see sensors (all 10k ohm) in the drawings listed as:
S-1 Flow – this is the leaving water from the heater/boiler.
S-2 Return – this is the entering water to the heater/boiler.
S-3 External – this is the storage tank sensor on water heaters and the common loop/low loss header sensor on boilers.
S-5 Tank – this is the Domestic Hot Water sensor on a heating boiler application only.
S-6 Outdoor – the is the sensor to be mounted outdoors for temperature reset control on a heating boiler application only.
PUMP CONTROL
• All water heaters and boilers are designed to operate with their own 240v pump that will be controlled and the
power to it supplied by the internal wiring.
• If a second 240v pump or diverting valve is utilized, the control is by the FMT 914, but the power
 tothepumpordivertingvalvemustbesuppliedandswitchedthroughaeldsuppliedrelayifthetotalwattage
draw exceeds 550 for all pumps (an additional wiring harness (P/N WRE 74090) is required on all pre-universal
heating models; please refer to our technical bulletin TB025, “EVO Universal Model: Starting Serial Numbers”,
to determine whether your unit is universal or not).
• Standard post burn cycle running of the pumps is as follows:
Water Heater – 1 minute Pump P3
Heating Boiler – 5 minutes Pump P1
Domestic Hot Water heating zone pump – 1 minute – Pump P2/Diverting Valve
Zone/Transport Pump – 5 minutes Pump P3

CONFIGURATION #1
Conguration #1 – DOMESTIC WATER HEATING (DHW) – model prex HWD
STAND ALONE WATER HEATER
• If an external temperature sensor (10k ohm thermistor) is connected to terminals 1 & 2 (or 3 & 4, 28 & 29
depending on model), the heater will be automatically controlled by this sensor.
• If an external temperature sensor is not connected to terminals 1 & 2 (or 3 & 4, 28 & 29 depending on model),
the heater will be controlled by its own inlet (return) temperature sensor. If there is no external sensor
connected, the water heater pump P3 must be running constantly.
 Inthiscongurationthefollowingcanbedone:
1. Adjust the heater minimum and maximum temperature setting via the red wheel located on the display
panel, within the range of 50 – 159°F (Parameter 2 EA, 2 EB)
2. An external on-off tank thermostat instead of the 10k ohm thermistor can be connected to terminals 5 & 6
(or 13 & 14, 57 & 58 depending on model). If a standard tank thermostat is used, there will be no modulation.
 Inthiscongurationthefollowingcannot be done:
1. Three way valves cannot be utilized.
2. A second pump cannot be controlled.

CENTRAL HEATING
CENTRAL HEATING (CH) – Model prex HWH
Inthesecongurationstheroomthermostatreferencecanbea:
On/off—Thermostatisconnectedandtheinputisclosed.Theowsetpointtemperatureisdeterminedbyaheatcurve.
TheheatcurvedeterminestheowsetpointtemperaturebyusingthetemperatureofS6(outside)(terminals1&2or
9&10,26&27dependingonmodel).Whennooutsidesensorisconnected(automaticallydetected),theowsetpoint
temperature is determined by the red wheel setting.
*Power being switched is 30 VDC. Connection is made at terminals 5 & 6 (or 13 & 14, 57 & 58 depending on model) (X1–9,18).
Note: if this circuit is not opened pump P3 will run all of the time except during a call for DHW. This circuit
should also be used for warm weather shut down, night set back etc.
OpenTherm—Thermostatisconnectedandtheinputisclosed.Theowsetpointtemperatureisdeterminedbythis
modulating thermostat utilizing the heat curve as described below in Outdoor reset. If no outdoor sensor is present, it is based
in setpoint. The thermostat sends the setpoint temperature to the FMT 914. Connection is made at terminals 5 & 6 (or 13 &
14, 57 & 58 depending on model); this requires the use of the optional OpenTherm Bus, two wire communication board.
0-10Vdc—Thermostatisconnected.Theowtemperatureisdeterminedbyconvertingtheinputvoltagetoaow
setpoint temperature. When the measured voltage is below 1-volt heat demand will end. Connection is made at terminals 7 & 8
(or 30 & 31 depending on model).
Outdoor Reset—Boiler water temperature can be controlled automatically based on outdoor temperature if a 10k ohm
thermistor is connected to terminals 1 & 2 (or 9 & 10, 26 & 27 depending on model). The control will automatically sense
thepresenceofthesensor.Whenanoutsidetemperaturesensorisconnected,theowtemperaturewillbeset,ina
linear way, from the outside temperature, in accordance with the equation: Tow = (40 – Parameter Data) K + Z (°C)
It is adjustable with two levels of settings:
a) Installer level: At this level it will be possible to change the angle of the heat curve, that is the K – factor (reset ratio),
plus the minimum water temperature (p = 2 ET) at the outdoor temperature you want heating to begin (p = 2 EP).
Minimum water temperature should be based on the type of radiation used for heat distribution. To operate at this level,
you will need a laptop or PDA with the appropriate SIT software.
b) User level: The user can adjust the boiler water temperature by a parallel shifting of the heating curve when
adjusting the red potentiometer wheel. This is the Z factor and has a programmable range from 0 – 20°C (36°F)
(factory default is 20°C 36°F), which allows for a + 10°C to a -10°C from center position adjustment.
Note: the maximum temperature setting (parameter 2EP) does not shut the boiler down, it sets the curve only!
Calculating required Parameter inputs:
1. Determine maximum outdoor temperature for specifying a corresponding water temperature.
2. Determine the minimum water temperature that will work at the above temperature.
3. Determine the design outdoor temperature of the heating system.
4. Determine the design water temperature to satisfy the radiation style at design air temperature.
Dividing the difference of the two water temperatures by the difference of the two air temperatures equals the “K” factor.

2. Outdoor temperature reset can be enabled by connecting a 10k ohm sensor to terminals 1 & 2 (or 9 & 10,
26 & 27 depending on model) – this will be automatically sensed by the FMT 914; see instructions Page 5
of this manual.
3. Pump P3 can be controlled based on the Room Thermostat must add heating harness WRE74090 and
wire to P3 leads. Caution: Maximum available wattage for external load on the FMT 914 control board
is 550 watts. If pumps P1 & P3 total less, they both can be powered directly off the board. If not, a
relay (240v coil) must be used for pump P3.

• A room thermostat is to be connected to terminals 5 & 6 (or 13 & 14, 57 & 58 depending on model) of the LEAD
BOILER ONLY. If no yellow jumper wire is attached to 5 & 6 (or 13 & 14, 57 & 58 depending on model), which
will be removed to connect room thermostat, additional wiring is required. Consult local supplier.
 •InthiscongurationanexternalsensororaquastatMUSTbeconnectedtoterminals1&2(or3&4,28&29
depending on model) on the LEAD BOILER ONLY to sense common loop temperature (after/at low loss header).
• The tank sensor or aquastat is to be connected to leads labeled “Tank Sensor” on the Lead boiler.
• The DHW pump is to be connected to the harness leads labeled “L and Close” in the Lead boiler, be sure and
cap the wire labeled “Open”.
 •Aowcheckmustbeinstalledonthedomestichotwaterloopandtheheatingloop.
 Inthiscongurationthefollowingcanbedone:
1. Adjust the boiler minimum and maximum temperature setting via the potentiometer located on the display
panel, within the range of 50 - 192°F. (Parameter 2 EB, 2 EA )
2. Set boiler water temperature to the DHW tank. (Factory default is 185°) (Parameter 2 CE)
3. Set the DHW water temperature (Factory default is 140°F (must be less than 2CC)). (Parameter 2 LF)
4. Pump P3 can be controlled based on the Room Thermostat, wire to P3 leads. Caution: Maximum available
wattage for external load on the FMT 914 control board is 550 watts. If pumps P1 & P3 total less, they
both can be powered directly off the board, if not a relay (240v coil) must be used for pump P3.
It is important to set the red potentiometer wheel to the desired setpoint on the Lag boilers with the power off to
the Lead boiler. This way, in the event of a control or power failure to the Lead boiler, the Lag boilers will operate
at the desired temperature.
