Installation and service instructions for contractors VIESMANN Electronic temperature differential control unit Vitosolic 200 Type SD4 For applicability, see the last page VITOSOLIC 200 1/2012 Please keep safe.
Safety instructions Safety instructions Please follow these safety instructions closely to prevent accidents and material losses. Safety instructions explained Danger This symbol warns against the risk of injury.! Please note This symbol warns against the risk of material losses and environmental pollution. Note Details identified by the word "Note" contain additional information. Target group These instructions are exclusively designed for qualified contractors. Work on electrical equipment must only be carried out by a qualified electrician. The system must be commissioned by the system installer or a qualified person authorised by the installer. Regulations Observe the following when working on this system: National installation requirements Legal instructions regarding the prevention of accidents Legal instructions regarding environmental protection The Code of Practice of relevant trade associations All current safety regulations as defined by DIN, EN, DVGW, VDE and all locally applicable standards a ÖNORM, EN and ÖVE c SEV, SUVA, SVTI and SWKI Working on the system Isolate the system from the power supply (e.g. by removing the separate fuse or by means of a mains isolator) and check that it is no longer 'live'. Safeguard the system against unauthorised reconnection. Please note! Electronic assemblies can be damaged by electrostatic discharges. Before beginning work, earthed objects, such as heating or water pipes, must be touched to dissipate any static charge. Repair work! Please note Repairing components that fulfil a safety function can compromise the safe operation of your system. Replace faulty components only with original Viessmann spare parts. 2
Safety instructions Safety instructions (cont.) Auxiliary components, spare and wearing parts Please note! Spare and wearing parts that have not been tested together with the system can compromise its function. Installing non-authorised components and making non-approved modifications or conversions can compromise safety and may invalidate our warranty. For replacements, use only original spare parts supplied or approved by Viessmann. 3

System examples General information Anti-scalding protection Danger Subject to system configuration, DHW temperatures above 60 C can occur. DHW with temperatures in excess of 60 C can cause scalding. To limit the temperature to 60 C, install mixing equipment, e.g. a thermostatically controlled mixing valve (accessory). Install a mixer tap as anti-scalding device at the draw-off point. Equipotential bonding and lightning protection of the solar thermal system Install an electrical conductor on the pipework system of the solar circuit in the lower part of the building in compliance with VDE [or local regulations]. The connection of the collector system to a new or existing lightning protection system or the provision of local earthing must only be carried out by authorised trained personnel, who must take into account the conditions applicable on site. Additional function for DHW heating For function description see page 100. DVGW W 551 specifies that the total water content must be maintained at 60 C and the pre-heat stages must be heated once every day to 60 C. Systems with a cylinder capacity, incl. DHW preheating stages, in excess of 400 l Systems with a line content in excess of 3 l from the DHW cylinder to the draw-off point We recommend heating up in late afternoon. This ensures that the lower cylinder area or the pre-heating stage is cold again following the expected drawings (evenings and the following morning) and can subsequently be heated up again by solar energy. Note For detached and two-family houses, this heat-up is recommended, but not compulsory. 6

Protect the cable to the control unit with an appropriate fuse/mcb. Disconnect the system by means of a device that simultaneously separates all non-earthed conductors with at least 3 mm contact separation. We additionally recommend installing an AC/DC-sensitive RCD (RCD class B ) for DC (fault) currents that can occur with energy efficient equipment.

Type" Delivered condition: 1 2. Adjust the pump type (see page 87). 3. Enable speed control if required (see page 87). 4. Set the solar options (see from page 89). This determines additional relay and sensor input assignments. 5. Set the system options (see from page 100). This determines additional relay and sensor input assignments. 6. Set special functions (see from page 107). Note All parameters are reset to their delivered condition when the setting for "System" is changed. Information regarding the relays Functions for which the same relay output is used can only be implemented as alternatives. Example system 1 (see page 67): The function "Par.Relay" (parallel relay) can only be enabled when no "Add. fct." (additional function for DHW heating) is active. 64
