Thermona THERM EL 38
Code: 1605Product detailed description
Electric boiler with output modulation Thermona THERM EL 38
The THERM - EL electric boiler is designed by its construction for hot-water heating systems with forced water circulation. It can be installed in central and single-storey heating systems with forced circulation, in open or closed systems. It is an ecologically clean operation with no flue-gas discharge requirements. Unattended operation is enabled by an external controller or yesther external control/operating element (not included in the boiler's scope of delivery); alternatively, a simple weather-compensation controller or a room temperature controller built directly into the control automatics, maintaining a preset temperature in the selected room, can be used. The electric boiler can be used as a universal heat source for heating in apartments, small family houses and recreational buildings, as well as an alternative source when yesther main heating and hot-water source is used (even for a transitional period) - for heat pumps, accumulation systems, or in previously installed single-storey and central systems, etc. For higher outputs, the boilers can be linked into cascades.
Main advantages of THERM EL electric boilers:
- top-of-the-range microprocessor control
- very quiet operation (switching power relay for heating elements)
- automatic air-vent valve (2 pcs - boiler body + pump)
- option to heat a DHW tank (terminals for an external three-way valve, NTC temperature sensor or tank thermostat)
- modern design
- ergonomic, interactive digital control
- smooth control in 2.5 kW steps (5 kW for the higher output range)
- service-adjustable pump overrun
- pump anti-seizing protection
- PID control
- anti-freeze protection (of the boiler and the system)
- option to connect an external NTC sensor (built-in weather-compensation control)
- connection of a room NTC temperature sensor (automatics acting as a room controller)
- built-in safety switching contactor for all power phases
- option of intelligent cascade connection of all boiler types (up to 32 boilers - with smooth output modulation)
- option of external control via GSM (external modem required)
- option to connect an external OpenTherm-communication controller - a room controller e.g. CR 04 or PT 59, or a higher-level Siemens RVS system
- even loading of heating rods and heating elements
- the power relays are not part of the processor PCB (easy servicing, replaceability); special relays with integrated fastons are used, i.e. high currents do not flow through the printed circuit board
- boiler switching system using an HDO signal (mass remote control / off-peak tariff switching)
- support for external power-input control (load-shedding relay)
- soft start
- integrated three-speed Grundfos UPS 15/60 pump
- integrated 7 l expansion vessel (for the lower output range)
- integrated topping-up and draining of heating water
- integrated safety valve
- digital heating-water pressure sensor (on all types)
- self-diagnostics, unambiguous service reporting of fault states
- option to set boiler parameters (extensive user and service menu)
- digital 3-digit display (shows the set temperatures, pressure, output, fault and other messages)
- 7 additional LEDs for clear signalling of operating states
- default option (immediate switch to factory settings)
