HT4tz Information
The HT4tz is a vertical thermostat that is one of Heatwell's dual purpose thermostats. The HT4tz is designed to operate underfloor heating and heated towel rails with the same thermostat.
Underfloor heating and towel rails can be operated independently.
Zone 1 controls the underfloor heating. Zone 2 controls the heated towel rails.
If you do not need independent programming for underfloor heating and heated towel rails, please have a look at the very easy to program HT4t.
All HT4tz's come preprogrammed, and are tested in New Zealand.
