JUMPER IN POSITION 6: unused

The boiler is supplied standard with the jumper in position 3 (standard heating + indirect water tank with thermostat); if you wish to use an external water tank with sensor, move this jumper from position 3 to position 2 (case B, Fig 61); if you wish to have low temperature for floor space heating move the not inserted jumper in position 1 (Fig 61).

16.SETTING THE OUTDOOR RESET CURVE WITH OUTDOOR SENSOR

Outdoor temperature reset only works with the outdoor air sensor connected, therefore, after installation, connect the outdoor air sensor to the relative connections on the boiler terminal board (Fig. 35).

This enables the outdoor temperature reset function.

The user can program the desired supply temperature based on the heat transmitter that will be used in the installation. Once the outdoor sensor is connected to the control board, the water temperature of the boiler will adjust to run the boiler more efficiently and provide greater comfort to the living space.

NOTICE: The DHW temperature is independent from the outdoor air sensor.

Selecting the offset heating curve (Fig. 65)

The offset heating curve maintains a theoretical ambient tempe- rature of 68°F (20°C) at outdoor temperatures ranging from 68°F to -4°F (+20°C to -20°C). The choice of the curve depends on the rated minimum outdoor temperature (of the geographical area) and the rated delivery temperature (on the type of system) and must be carefully calculated by the installer using the following formula using the correct values in °F or °C:

TMR =

 

Nominal flow Temp. - Tshift

 

 

68°F (20°C) - min. external design Temp.

 

 

Tshift =86°F (30°C) standard systems (radiators) 77°F (25°C) underfloor systems

If the calculation generates an intermediate value between two curves, choose the nearest offset heating curve to that value. E.g.: if the value obtained by the calculation is 1.3, it lies between curve 1 and curve 1.5. In this case, select the nearest curve, i.e.: 1.5.

Select KT by turning the trimmer located under the domestic hot water temperature knob (A).

The settable values of KT are:

-standard system: 1,0-1,5-2,0-2,5-3,0

-floor system: 0,2-0,4-0,6-0,8

TYPE OF HEAT REQUEST

STANDARD

If a room thermostat is connected to the boiler: room thermostat

The room thermostat makes a heat request when its contact closes, while it stops it when its contact opens. Though delivery temperature is automatically calculated by the boiler, the user may manually override it. By modifying HEATING on the user interface (C), the HEATING SET POINT will no longer be available but just a value that can be set from +5 to -5 as required. Please note that the number displayed is a comfort level: +5 means feel hotter, -5 means feel colder. Modifications to this value do not directly change flow temperature but affect the calculation made to automatically determine its value by modifying the reference temperature of the system (0 = 68°F (20°C)).

PROGRAMMABLE TIMER (DAY+NIGHT)

If a programmable timer (day+night selector) is connected to the boiler, set parameter 51 = 1 (this parameter can only be modified from the remote control unit) (Fig. 67) available only from Raypak technical service.

When the contact is closed, the heat request is made by the delivery probe on the basis of the external temperature in order to maintain the rated ambient temperature at the DAY level 68°F (20 °C). When the contact opens, it does not stop the heat request but reduces (parallel shift) the temperature curve to the NIGHT level 61°F (16 °C).

This activates the night mode.

Though flow temperature is automatically calculated by the boiler, the user may manually override it.

By modifying HEATING on the user interface (C, Fig. 13.2), the HEATING SET POINT will no longer be available but just a value that can be set from +5 to -5 as required. Please note that the number displayed is a comfort level: +5 means feel hotter, -5 means feel colder.

Modifications to this value do not directly change flow tempera- ture but affect the calculation made to automatically determine its value by modifying the reference temperature of the system (0 = 68°F (20°C) for DAY level; 61°F (16°C) for NIGHT level).

If a remote control (Raypak REC 08) is installed refer to instructions for setting the outdoor sensor using.
