3.2 Sensor configuration.
There are three sensor operating configurations; 1. floor sensor & room sensor control, 2. floor sensor only control and 3. room sensor only control (simple
thermostat). The operating configuration is initially selected by the DIL switch during installation but can be changed later under the configuration menu
without having to open the control. If the installer erroneously sets both sensor DIL switches to off then the control will default to floor sensor only mode.
When floor and room sensor configuration is chosen the control acts as a thermostat to control the room temperature to the comfort or savings
temperatures which have been set. The floor sensor is used to control minimum and maximum floor temperatures (at the sensor position), the minimum
floor temperature applies during comfort and saving periods. An energy saving feature is also incorporated so that the room temperature target is adjusted
down by 0.1 deg for every 1 deg that the floor temperature is above the room temperature set point - this feature takes account of the way occupants ‘feel’
the temperatures.
•
When floor and room sensor configuration is chosen, the display will show the room temperature. The floor temperature can be checked by
using the menu button.
•
When floor sensor only operation is chosen the control acts as a thermostat to control the floor temperature to the comfort or savings floor
temperatures that have been set. The maximum floor temperature is used to limit the comfort and savings temperatures that can be set.
•
When floor sensor only configuration is chosen the display will show the floor temperature. The room temperature is not displayed as the control
may be located in a different room (e.g. in a hallway outside the bathroom).
•
When room sensor only configuration is chosen the control acts as a thermostat to control the room temperature to the comfort or savings
temperatures that have been set.
•
When room sensor only configuration is chosen the display will show the room temperature.
3.3 Timer period day mode configurations (timed mode only).
There are three different timer period day modes that can be can be set.
•
In 1 day mode no days are shown and the same timer periods are used for all days.
•
In 5:2 day mode the days are grouped into weekdays and weekends and one set of timer periods apply to all week days (Monday, Tuesday,
Wednesday, Thursday and Friday) whilst another set of timer periods apply to all weekend days (Saturday and Sunday).
•
In 7 day mode each day has its own set of timer periods and each can be different.
All timer period configurations offer 4 timer periods per day.
3.4 Maximum floor temperature.
The maximum floor temperature is initially set by DIL switch during installation. The choices are wooden floor, giving 28°C maximum floor temperature, or
concrete floor, giving 35°C maximum. This can be changed later under the configuration menu without having to open the control.
3.5 Minimum floor temperature.
A minimum floor temperature can be set by the user, this minimum applies during all time periods - comfort or savings - but not when the control is off or
during frost protection. The minimum floor temperature is ignored if the sensor configuration is room sensor only.
3.6 Control temperatures (timed modes only).
There are two control temperatures when the control is in timed mode.
•
Comfort temperature applies during timer periods 1 & 3
•
Savings temperature applies during timer periods 2 & 4
3.7 Temperature modes.
There are five different temperature modes available when the control has been configured for timed mode operation. These are: timed (using timer periods
plus comfort and savings temperatures), constant comfort, constant savings, frost protection (with temperature fixed at 5°C) and off.
There are three different temperature modes available when the control has been configured for un-timed mode operation. These are: constant
temperature, frost protection (with temperature fixed at 5°C) and off.
3.8 Tamper proof locking of temperature adjustment.
For enhanced safety a tamper proof lock can be enabled to protect the control temperatures, frost protection, off mode and continuous operation modes
from adjustment.
When tamper proof lock is enabled the PADLOCK icon is visible; the
S
and
T
buttons do not adjust the temperature of the control, the O/I button and the
24h button does not respond.
When tamper proof lock is disabled the PADLOCK icon is clear; the
S
and
T
buttons can adjust the temperature of the control, the O/I button responds
and the 24h button responds.
3.9 Heater hours usage meter.
The control keeps a log of the usage of the heater which can be displayed for information purposes. The display shows the number of hours that the heater
element has been on. The control displays the heater usage time for today, yesterday, last week and total use. The total use counter can be reset to 0000.
