User instructions - General information.
A) What HC10B does
HC10B is a digital thermostat for precise control of electric underfloor heating.
HC10B starts automatically in Quickstart = Manual mode and floor sensor
HC10B can also perform night and day setback in three different ways
B) IMPORTANT!
Important information before connecting the underfloor heating
To ensure optimum service life of the underfloor heating, the material in which the heating system is laid must be allowed to
dry for a minimum of 28 days before switching on the heat.
A new installation of HC10B and underfloor heating must be carried out by an authorised electrician.
Exchanging an HC10B, is allowed to do by the end-user in most countries.
HC10B must not be covered
C) Programs in HC10B
C1) Quickstart
Switch on and the underfloor heating will start up.
The temperature is set to 21
O
C
The temperature can be altered with [▼] and [▲]
The display shows the set temperature
The floor sensor will automatically start operation
C2) Night and day setback programs
HC10B holds three different night and day setback programmes.
They each control the temperatures and time settings. i.e. low temperature at night and during working hours, higher
temperature at morning and evening.
For each program the starting time and temperature are determined. Start times and temperatures are set at the factory, but
can be changed as required. The factory setting is shown in Table 1.
Night and day setback ensures minimum power consumption. With optimum adjustment of the underfloor heating the average
temperature can be dropped by up to 3
o
C, giving potential power savings of up to 15%. The savings will naturally depend on
the circumstances and on what you want from the underfloor heating.
Max. and min. limits are in all programs Max: 27
