PROGRAMMING MANUAL – UNIVERSAL ELECTRONIC WEEK TEMPERATURE CONTROLLER – ROOM

Characteristics of the universal electronic week temperature controller – room After proper installation and connection, the temperature controller automatically shows the time of day and room temperature. In AUTO operation mode, heating (cooling) will be automatically turned on, according to the programmed time and temperature. Program 1 is the program set by default. The room temperature is adjusted based on the temperature measurement taken by the internal sensor. The heating will turn on as the temperature drops below the level of the setpoint.

The week room temperature controller can be used to control the room temperature in combination with : – thermal actuators, such as underfloor water heating or convector heaters, – oil or gas radiators, – circulation pumps, – heat pumps, – electric convector heaters, ceiling heating and storage heating.

Connecting a probe (SO-1) To measure the room temperature, instead of an internal sensor, you can use a probe (SO-1). Probe selection can be made in the menu, see H1. The probe should be placed in the electrical conduit (which will facilitate replacement if necessary). The probe can be extended using cables or connections for 230V to a maximum. 50 m. Avoid running the probe cables parallel to the power cables, such as in the cable duct.

Notice! The probe wire may be under mains voltage.

Defined programs The temperature controller has three defined programs for temperature control at specific time intervals. at the user’s disposal. Program 1 is specified as standard. To select another program (see G1).

PROGRAMMING MANUAL – UNIVERSAL ELECTRONIC WEEK TEMPERATURE CONTROLLER – FLOOR

Characteristics of the universal electronic week temperature controller – floor After proper installation and connection, the temperature controller automatically shows the time of day and room temperature. In AUTO operation mode, the heating will be automatically turned on, according to the programmed time and temperature. Program 1 is the default setting, the temperature is adjusted based on the floor temperature, and the heating will turn on automatically when the floor temperature drops below the level set on the thermostat and turn off when the specified temperature is reached.

The week temperature controller for underfloor heating can be used to control the temperature in combination with : – direct heating, – underfloor heating system.

Connecting the probe (SO-1) The probe should be placed in the electrical conduit (which will facilitate replacement if necessary). The probe can be extended using cables or connections for 230V to a maximum. 50 m. Avoid running the probe cables parallel to the power cables, such as in the cable duct.

PROGRAMMING MANUAL – UNIVERSAL ELECTRONIC WEEK TEMPERATURE CONTROLLER – LIMITER

Characteristics of the universal electronic week temperature controller – limiter After proper installation and connection, the temperature controller automatically shows the time of day and room temperature. In AUTO operation mode, the heating will be automatically turned on, according to the programmed time and temperature. Program 1 is the program set by default. The room temperature will be adjusted and the floor temperature will be limited (measured by the remote sensor). The heating will turn on automatically as the temperature drops below the setpoint. In the case of the “Minimum floor temperature” function, the heating will turn on if the floor temperature falls below the set minimum value. This is the case even when the room temperature is too high. In the case of the “Maximum floor temperature” function, the heating will turn off if the floor temperature exceeds the set maximum value. This is the case even when the room temperature is too low. The week temperature controller for underfloor heating can be used to control the temperature in combination with : – electric floor heating systems, where the floor temperature must be within a certain range of values, – hot water-fed floor heating systems in combination with thermal actuators.

Probe connection (SO-1) When using the “LIMITER” mode of operation, the temperature controller requires using a probe (SO-1). The probe should be placed in the electrical conduit (which will facilitate replacement if necessary). The probe can be extended using cables or connections for 230V to a maximum. 50 m. Avoid running the probe cables parallel to the power cables, such as in the cable duct.

You can select the type of PWM or ON/OFF signal. For PWM, you can set the cycle me (in

PWN/10

minutes). Minimum ON/OFF me = 10% of cycle me. Use a short me for hea ng systems with fast (/10…30)

response mes, and a longer me for slow-response systems.

For ON/OFF, you can select:

– Hysteresis

OFF – no hysteresis se ng, even in the case of very small temperature changes, the relay will switch OFF (OFF,

Limits the temperature of the floor. Possible selec on: – minimum floor temperature that does not drop below the set temperature (OFF = no limit); Mintemp. = 21°C, the floor temperature does not drop below 21°C, even if the room is too warm. – maximum floor temperature that does not rise above this set temperature (OFF = no limit); Maxtemp. = 35°C, the floor temperature does not exceed 35°C, even if the room is too cold. If one of these restric ons is not needed, set it to OFF.

Errors In this situation, “Err” will be flashing on the screen, possibly indicating the following error: 1. CONFIGURATION – the display and module do not match: – use only suitable parts, – turn the power off and on. 2. COMMUNICATION – communication error between the display and the power module: – remove the upper part and reconnect, – turn the power off and on. 3. EXTERNAL SENSOR (PROBE) – remote sensor error – sensor replacement – measurement span exceeded. In case of any of the foregoing errors, heating will be on for 30% of the time.
In case of the ROOM mode of operation: if H4 = HEAT: heating will be on for 30% of the time, if H4 = COOL: no cooling.
