SET HIGH BOILER TEMPERATURE SETPOINT FOR THE VALVE (6)
TO INCREASE RETURN WATER TEMPERATURE! TO IMPROVE
WATER CIRCULATION IN THE GRAVITY CIRCUIT (IN BOLD LINES):
USE HIGH NOMINAL PIPE OR FOUR-WAY VALVE DIAMETER, AVOID
BENDS AND REDUCTIONS IN DIAMETER, MAINTAIN MIN. 2°
GRADIENT ETC. IF THE SENSOR (3) IS ATTACHED TO THE PIPE,
USE FOAM INSULATION (14) COVERING BOTH THE SENSOR
AND THE PIPE.
