i have taken the batteries out of the sender so a red light shows on the receiver
with the batteries in the boiler fires with a green light on the unit
last night i ran the heating and the control went off after an hour with the switch still in the off pos'n

the boiler is a worcester bosch greenstar 30si

checked all the rads they seem normal

These are different frequency bands. The IP conflict should resolve itself. Probably has already.
