Model HCT2 Cylinder Thermostat
W ith an adjustable temperature range of between 20oC and 90oC, the HCT2 Cylinder
thermostat is suitable for mounting on either domestic hot water cylinders or larger diameter heating pipes.
Features
A bimetallic sensor ensures accurate switching and control.
A strap is included for easy fixing to cylinder.
Installation Instructions
The HCT2 should usually be strapped on to the cylinder at a height of about one-third up
from the base - the strap should be tight for good thermal contact. It should be adjusted to
around 60oC. If set too high it may give rise to scalding, and if set too low it will increase
risk of the growth of legionelle bacteria, which could lead to serious heath problems.
