Chronothermostat with Humidistat User Manual
REGULATION TYPE
The default regulation type is ON/OFF with deactivation in correspondence
with the setpoint and with differential set to 0.3°C.
During on/off operation mode, the output relay follows the following logic:
relay ON
SET-DIFF SET
relay OFF
Temperature
increasing
relay ON
SET+DIFFSET
relay OFF
Temperature
increasing
heating mode / humidification cooling mode / dehumidification
During heating mode the proportional regulation can be chosen; in certain types
of systems, this allows to improve the regulation, in order to obtain a constant
temperature.
This regulation activates the ON or OFF relay within a predefined regulation cycle on
the basis of the gap of the temperature measured by the setpoint value.
The necessary parameters for the definition of this mode are:
• the regulation band
• the regulation period
The regulation band represents the temperature interval, centered on the setpoint, in
which the proportional regulation is checked.
Half the desired regulation band is set in the device.
The range for this parameter is 0.5 ÷ 5.0°C with 0.1°C resolution
The regulation period represents the duration of the regulation cycle (activation period
+ deactivation period)
The value of this parameter is selectable between 10', 20' and 30'
Choose the regulation period value as follows:
• 10' for low thermal inertia systems
• 20' for medium thermal inertia systems
• 30' for high thermal inertia systems
