Can I have CH only?

The advantage of having just CH selected is that you save money by not heating domestic hot water
- the disadvantage is that you have no hot tap water.

Much will depend on your specific boiler installation.

***********************


Your installer should have set the LP522 to suit your
heating system. If this is one which does not permit you to have CH without HW you will find the LP522 does not allow this to happen.

If you have a fully pumped and controlled system then
you will be able to operate heating and hot water
independently.

The LP522 gives you 4 options for both CH and HW:
OFF - Off all the time
TWICE - On for two periods each day
ONCE - On for one period each day (ON1 -> OFF2)
ON - On all the time

Remember some hot water systems do not allow CH to
be ON without HW being ON.

Obtain the options you require by using the SELECT
buttons to move the arrows in the display to the appropriate positions. Your programmer is now working using the standard programme times.
