Modulating Models
Water heaters with modulating operation are fitted with an RWF40
adjustable controlling thermostat with the temperature sensor located in
the outlet side of the header.
This type of control is used where the system load is variable e.g.
Mechanical Heating.
This type of control will cycle the burner from full fire to 30% and then off.
The thermostat has a number of parameters that are programmed during
manufacture (refer to the 'RWF40 Parameter Table' on page 32 for
values); advice should be sort from your local Raypak representative prior
to altering any values other than the set point or the differentials.
To adjust the Set Temperature (SP1)
1. Press and release the 'PGM' button momentarily, 'SP1' and the
current set point will be displayed.
2. Press the ▲ button to increase the set point value or the ▼ button to decrease the set point
value.
3. Press and release the 'PGM' button momentarily to accept the new setting
4. Press and release the 'EXIT' button
