Definitions

NOTE: The defined terms are not active in all modes of control operation.

%OUT - Current percent modulation rate of heater.

BOIL DSGN - Design boiler water temperature used in heat loss calculations.

BOIL MASS - This setting allows adjustment in the field for high or low thermal masses; High thermal mass (setting=3) provides slower reaction, lower ther- mal mass (setting=1) provides faster reaction.

BOIL MAX - Highest outlet water temperature that the control is allowed to use as a target temperature.

BOIL MIN - Lowest outlet water temperature that the control is allowed to use as a target temperature.

BOIL ON - Accumulated runtime of heater (up to 999 hours, then resets to 0).

BOIL OUT - Actual heater outlet water temperature. BOIL START - Starting boiler water temperature. BOIL SUP - Actual system supply water temperature.

BOIL TARGET - Target temperature that the heater is trying to maintain.

‘BURNER’ DELAY - Holds control output at ignition setting from the start of the ignition sequence to the specified burner delay time (0 to 3:00 min.).

DEM 1 - Indicates 24 VAC signal has been supplied to the H+D terminal.

DEM 2 - Indicates 24 VAC Flame Proof signal is pres- ent.

DIFF - The operating differential of the heater; The heater outlet water temperature is allowed to rise above the BOIL TARGET temperature by 1⁄2 of this dif- ferential before the heater shuts off. For example, if the heater target temperature is set to 160°F (71°C) and the differential is set to 10°F (5°C), on temperature rise, the heater will shut off at 165°F (74°C). Once the heater shuts off, it will not come on again until the tem- perature falls to 155°F (68°C).

EXTERNAL INPUT SIGNAL – Selects external input signal range (0-10VDC or 2-10VDC):

0-10VDC or 0-20 mA external input signal – When the 0-10VDC signal is selected, an input voltage of 1 VDC corresponds to a boiler target temperature of 50°F (10°C). An input voltage of 10 VDC corresponds to a boiler target temperature of 220°F (104°C). As the voltage varies between 1 VDC and 10 VDC, the boiler target temperature varies linearly between 50°F (10°C) and 220°F (104°C). If a voltage below 0.5 VDC is received, the boiler target temperature is displayed as “– – –” indicating that there is no longer an internal heat demand. A 0-20 mA signal can be converted to a 0-10 VDC signal by installing a 500 resistor on the external input signal device’s terminals.

2-10VDC or 4-20 mA external input signal – When the 2-10VDC signal is selected, an input voltage of 2 VDC corresponds to a boiler target temperature of 50°F (10°C). An input voltage of 10 VDC corresponds to a boiler target temperature of 220°F (104°C). As the voltage varies between 2 VDC and 10 VDC, the boiler target temperature varies linearly between 50°F (10°C) and 220°F (104°C). If a voltage below 1.5 VDC is received, the boiler target temperature is displayed as “– – –” indicating that there is no longer an internal heat demand. A 4-20 mA signal can be converted to a 2-10 VDC signal by installing a 500 resistor on the external input signal device’s terminals.

FP - Flame proof warning. Warns that the control did not see burner flame within 5 min. of call for heat.

MODE - Operating mode of the heater.

OFFSET - The Offset setting allows the boiler target temperature to be fine tuned to the external input sig- nal. The control reads the external input signal and converts this to a boiler target temperature. The Offset setting is then added to the boiler target temperature.

OUTDR - Outdoor air temperature.

OUTDR DESIGN - Design outdoor air temperature used in the heat loss calculation.

OUTDR START - Starting outdoor air temperature.

PUMP DLY - Sets the operating time of the pump once the CFH is satisfied.

TANK - Current DHW tank temperature (Mode 3). TANK DIFF - Storage tank differential (Mode 3).

TANK TARGET - Target temperature in the DHW storage tank (Mode 3).
